Analysis on Characteristics and Genesis of Xiaoyunpan Landslide in Zhenyuan,Guizhou Province
Xiaoyunpan landslide is a typical stratiform rock landslide in Guizhou province.Taking Xiaoyunpan landslide in Zhenyuan County,Guizhou Province as an example,the characteristics,genesis and evolution of Xiaoyunpan landslide are studied detailed.The results show that the volume of Xiaoyunpan landslide is 24.2× 104m3,which is a medium-sized rock traction landslide.The soft and hard interbedded strata structure is the sedimentary foundation of landslide formation,and extreme rainfall and human engineering activities provide external dynamic conditions.The formation of landslide goes through four stages:sedimentary formation stage of landslide formation,slope formation stage of geological tectonic action,formation stage of potential sliding surface and sliding failure stage of landslide bedding.The damage mode is that the front rock mass slides and disintegrates,and the middle and rear rock mass gradually pulls and slips along the bedding.
