The time is already autumn, and the weather is still very hot. As the first day of the internship, the first is the mobilization before the internship. The teacher briefly explained the contents of the internship. In the afternoon, under the teacher's organization, we collectively watched some film and television materials and learned a lot of bad geological phenomena, such as earthquakes, landslides, earth and rock flows, etc., and also watched several representative landforms, such as karst landforms, as textbook knowledge. The supplements allow us to understand the causes, consequences and consequences of various geological phenomena without going out, and also understand some measures and methods to prevent the occurrence of these geological phenomena, so that we have enhanced our understanding of geological phenomena. Also watched the common rock-forming minerals, the rock's occurrence, structure and structure, and understood their engineering geological characteristics. Although the film is not very clear, most of them were taken in the 70s and 80s, but after reading it, it has enhanced our Engineering geology expertise.

Today, the weather is fine. After watching the video materials and letting us know more about the geological phenomenon, we begin to learn to read the engineering geological map. In order to enable us to understand the characteristics of different inclined formations, fold structures and faults on geological maps, the teacher explained in detail the characteristics of horizontal rock formations, inclined rock formations, vertical rock formations, fold structures and faults on geological maps. But there are too many people, all around the teacher. The voice of the teacher is not very much, so the listening is not very clear. Combined with the content of the internship guide and part of the hearing, I have learned to read various geological phenomena from the geological map. Analyze the indexing law of geological phenomena, and also grasp the analysis methods of geological maps of folds, faults, unconformity structures and magmatic rock intrusion activities, and draw geological profiles from geological maps with geological structure maps, according to geology Figure shows the method of regional geological development history.

In order to be in a state of internship, I did not know what to do. I carefully read the internship instruction book and carefully read the courseware given by the teacher. I got a preliminary understanding of the importance of geological exploration in engineering construction and various methods and steps in engineering geological exploration. A comprehensive understanding of the contents of the engineering geological survey report.

In the site selection stage, after collecting regional geology, topography, earthquakes, building materials and other materials, in order to understand the site lithology, geological structure, rock and soil engineering properties, groundwater action and adverse geological phenomena, it is necessary to carry out field Field exploration, so the lotus field exploration was arranged.

I have heard about the scenic spots of Lianhua Mountain for a long time. Today, I finally have the opportunity to see its "Shenzhen True Face". Guangzhou Panyu Lianhua Mountain Scenic Area is located on the banks of the Lion River in Zhujiangkou, Panyu District, about 30 kilometers from downtown Guangzhou. It is a scenic tourist area that blends ancient rough and modern beauty. In XX, Lianhua Mountain was rated as a 4a level scenic spot by the National Tourism Administration. Lianhua Mountain has beautiful scenery and outstanding people. It is divided into: Lotus Tower Scenic Area, Lotus City Scenic Area, Guanyin Shengjing District and Shijing District. The stone scenic spot headed by the West is the ancient quarry site built in the Western Han Dynasty. It is famous for its cliffs, cliffs, and strange caves. It is famous for its "artificial unintentional work" and is known as the "Man-made Danxia" miracle. The mining time of the ancient quarry was continued from the early years of the Western Han Dynasty to the Daoguang Period of the Qing Dynasty. The stone material of the Western Han Dynasty Nanyue King was collected from Lianhua Mountain. It consists of more than 40 hills with an area of ​​more than 300,000 square meters. The Lianhuashan ancient quarry is mined by cutting rock drilling. The average height of the remaining quarry surface is 25 meters, the highest point is 40 meters, and the deepest is 13 meters below the ground. The quarry still retains the stone pillars, slate and a large number of stones that have not been removed during the ancient quarrying. The lotus tower built in the Ming Dynasty for 40 years is the representative of the lotus tower scenic spot. The Lotus Tower, also known as Wenchang Tower, is known as the “Provincial Chinese Table”. Standing on the tower, you can see the beautiful scenery on all sides. The Lotus City, which was built in the Kangxi three years in the Qing Dynasty, was originally used for the defense of the Qing government in the Pearl River Estuary. The vicissitudes of history condense in the ancient city of the ancient city, which is a reminiscent of the past one hundred years ago; within the Guanyin victory, the lotus flower blossoms, "the mud is not dyed, the sputum is clear and not the demon", Coupled with the golden body of the Wanghai Guanyin image, it is really extraordinary, it is like a "clean land", a sense of awe.

The structural position of Lianhua Mountain is located in the deep fault zone since the Caledonian movement. It was formed during the orogenic period of the Yanshan Movement in the Mesozoic, and is a typical fold mountain system. The Lianhuashan Mountain Range enters the Hua'an area of ​​Fujian Province in Fengshun, Meixian and Dapu in the northeast; to the southwest: to the Haifeng and Huidong Baoan counties in Daya Bay, Shenzhen Bay, such as the South China Sea, and again from the Wanshan Islands and Gaolan archipelago. Guangdong has a length of about 500km, a width of 20 to 40km, and a partial area of ​​60km. The deep fault is a strong crushing zone with more than 120 faults. It is divided into east and west faults. There are 13 trunk faults in the southeast and 14 trunk faults in the west. This kind of dynamic thermal metamorphism is strong, and it can find minerals such as lead, zinc, copper, tungsten and tin. It is an important guiding rock structure. There are many fracture-type intermittent eruptions in the medium-acid magma. Within the deep fault, there are more than 100 rock masses. It is a metallogenic belt of endogenous metal deposits.

Stratigraphy: The Jurassic system is collectively referred to as the Gaojiping Group. This group is a complex set of continental volcanic rock series composed of neutral, medium-acidic, acidic volcanic lava and corresponding volcanic clastic rocks and sedimentary rock interlayers.

In the morning of 10 or so, several classes of our civil engineering majors took the school bus to the Lianhua Mountain. The road to the mountain was steep, but the scenery along the way was good. The birds and flowers all the way, could not help but want to get off quickly and enjoy it. Finally arrived at the top of the mountain, after getting off the bus, we followed the teacher, listening to the teacher's explanation, while enjoying the beautiful scenery. The first thing that caught your eye was the Wanghai Guanyin, which was grand and magnificent. The Wanghai Guanyin gold statue is more than 40 meters high. This Guanyin is like the Xia lion sea and the lustrous Nantian. It is said to be the world's best foil gold and bronze statue. At this time, the sunset is just west, and the Guanyin is like a Buddha. On the right side of Wanghai Guanyin is the Guanyin Pavilion. It is an antique single building. It has three floors and is wide open, with a veranda. It is built according to the big wooden style of the Qing Dynasty. It is majestic and solemn, magnificent and antique. On the third floor, there is the plaque of "Lotus Temple". In front of the main hall, there is a large-scale incense case. The fragrant customers are sincerely burning incense and praying for blessing.

Going down the stone steps, you will arrive at the Lion Rock. It is a stone standing proudly, like a male lion. It is estimated to be named here. It is said to be one of the symbols of Lianhua Mountain. This stone was eroded by ancient sea tides. It seems that the water level is still high here thousands of years ago. The lithology of the stone is the brown-red sandstone of sedimentary rocks. The layered structure is obvious and it is very easy to be weathered.

Next is the Eagle Eagle Trail and Feiying Cliff. The Eagle Eagle Trail is an artificially excavated tunnel. The tunnel cave is relatively large and penetrates the entire rock formation. The rock lithology is the brown-red sandstone of sedimentary rocks, and the bedding structure is obvious.

We followed the teacher all the way. Opposite the Lion Rock is the Guanyin Rock. It is a rock that protrudes outward from the upper part and is recessed inward in the lower part. It has the words “Guanyin Rock” on it, and the lithology is also the brown red in the sedimentary rock. Sandstone, which is dedicated to a statue of Guanyin, many devout men and women worship in the top, as well as marriage, although I do not believe this, but in the face of the compassionate Guanyin Bodhisattva, I even want to ask for a sign, but Finally did not go, but followed the teacher. Next is the Eight Immortals Rock. The Eight Immortals Rock is actually a rock group with different shapes, but the lithology is brown-red sandstone. The rock bedding structure is obvious, the upper part is covered with plants, the leveling joints appear on the rock, the vertical joints, the inclined joints, and Wave joints, some joints run through the entire rock group. It is obvious that the rock is subjected to relatively large tensile stress and biological weathering.

In the process of watching, because there were too many people, we walked away, did not keep up with our team, but with the teacher of another class, we came to the bath Xianchi, listening to the teacher, this is a Precipitation and surface water are small pools formed in the lower reaches of the rock formation. The pool is artificially treated in an elliptical shape. On the side of the pool, it is a statue carved with white stones. It is a bit like the fairy goddess in Tianlong Ba Bu. The statue, the fairy sister's hairpin on the head, is preparing to bathe, and the bath fairy pond is named after it. Under the guidance of the teacher, we found that the sandy rocks around the pool have been blown by the winds of the sun and rain forests for a long time. The wild matter grows, and the weathering degree is strong. Some rock surfaces have been broken and cut, and the rock fragments in the lower part of the rock are weathered into powder and piled up. It is earthy and its engineering geological properties are extremely poor. This weathered rock should not be used as the foundation bearing layer of construction engineering.

We followed the teacher and went to the Bilian pool. Unfortunately, there is no lotus in the pool. Only the fish are swimming around. It is free and comfortable. It is also very happy. The Bilian pool pavilion and the corridors, the small bridge and the mountains and rocks On the high rock wall, there is a poem "How many floors are the first, the lotus swallows are smashed. In front of the lions, the waves are not in the water." On the rock behind the lotus pond, a statue of Guanyin carved in white jade is erected.

Going forward, you will go to Yanziyan. The Yanziyan is composed of two high-rise rocks. The two rocks are integrated into one. After the ancient quarry, the lower part is cut open, and two rocks rise above the surface. There is also a sightseeing pavilion on the top of Yanziyan. It looks very dangerous. There is a sloping joint on the rock, but these two fast rocks have not gone down for thousands of years, which is really amazing. Connected to the Yanziyan is the ancient quarry. This quarry has a history of more than 2,000 years. The cliffs and cliffs of the ancient quarry are strangely carved. It seems to be excavated by the gods. Known for its unique scenery and scientific value, the Shijing wonders are the miracle of the “Artificial Danxia”. The quarrying structure of the quarry in the ancient quarry is obvious, and the inclined joints are particularly prominent. The width of the quarry is long and the length is long. The bottom of the quarry forms a depression due to the low terrain, and the surface water is accumulated for many years to form a water lake.

The one-day internship ended like this. I originally planned to use the internship as a watersport, but I found that there is a harvest. This is a process of combining theory with practice. In this process, we must understand and apply the knowledge we have learned flexibly. In order to strengthen our understanding of this course, and in the process of internship, I learned a lot of things that could not be learned in books. The ancients said that reading thousands of books is not as good as traveling thousands of miles. It seems that this is the truth. Also thank the teacher for his careful guidance. Through this field internship, I also understand the truth: to have a certain understanding of the objects to be inspected, and to prepare in advance, you will not be overwhelmed when you arrive.
