The southwestern region of China is located in the periphery of the Qinghai-Tibet Plateau, near the east side of the collision zone between India and Eurasia plates. The geological structure is very complicated and the geological disasters are serious. Combined with the investigation, design, construction and operation of important trunk railway in Baosheng, Guikun, Chengkun, Xiangyu, Nankun, Nekun, Yuhuai and other areas with difficult geological conditions in Southwest China, the author summarizes the basic situation of geological disasters in Southwest China Railway More systematically introduced several major geological disasters of railway geological exploration and engineering control technology experience.
