    ANALYSIS ON THE DEVELOPMENT OF GEOLOGICAL DISASTERS ALONG LONGCHANG-HUANGTONG RAILWAY FROM XUYONG TO BIJIE

    • Longchang-Huangtong railway from Xuyong to Bijie is located in the transition zone between the sichuan basin and the yunnan-guizhou plateau, and is located in the slope area of the yunnan-guizhou plateau. Based on the detailed investigation of geological disasters along the railway, this paper summarizes the types of geological disasters along the railway. There are four major disasters: collapse, landslides, debris flow and potential unstable slopes, the disasters are mainly small scale. On this basis, the developing characters of disasters and distributing rules are studied. The results show that the geological disasters along the railway have significant spatiality and timeliness. The disasters are mainly occur in June to August and controlled by vegetation obviously. The disasters mostly located along the valley and in the area where human activities are frequent. The study is of great significance to the prevention and control of geological disasters along the railway.
