The Survey of Karst at Guizhou Section of Chengdu-Guiyang Railway

Abstract:

Guizhou section of Chengdu-Guiyang Railway is located in northwestern GuizhouPlateau, which belongs to Chishui River and Wujiang Drainage Area. Thegeologic structures are mainly the fold or fracture in the direction of North-North East, and have Flat rock. Carbonate rocks are widely distributed on the surface of this area. All kinds of karst pronounced,and water and soil conservation is very bad. Rocky desertification is serious, and environmental is sensitive. Karst is one of the main unfavorable geology of control line scheme. In this paper, from the regional geological environment and regional hydrological environment ,analysis of the factors influencing karst has been done. The development regularities of karstis summarized, and the corresponding classification standards are provided. Through the comprehensive analysis of each line program of geological factors,karst geological basis for the route plan is provided .
