Rock mass has undergone various complex geological processes in the whole geological history, and has complex structure and ground stress field environment. Different types of rock mass in different regions have great differences in engineering properties due to different geological processes. After the rock is exposed to the surface, it is weathered to form soil. They remain in the original place, or are eroded and transported by wind, water and glaciers and deposited in different places to form soil layers. The dynamics of weathering environment, transportation and deposition in different geological periods and different regions are different. Therefore, the engineering properties of soil are complex, and the regional and individual properties are very strong.
