Abstract

[Objective] Studying on the formation mechanism and risk assessment of typical soil landslide in South Qinling Mountains can provide technical support for the prevention of geological disasters in the region.[Methods] The Shanyang School landslide in Shaanxi was selected as an example

the formation conditions and distribution characteristics were analyzed through in situ investigation

survey and laboratory test.[Results] The results show that Shanyang School landslide is in a stable state

the landslide may be revive suffered extreme climates

and resurrection probability is 7.45%.[Conclusion] Regional differences in the crustal movement are the inner dynamic factor of the landslide

and rainfall is the main induced factor of landslide. The maximum personnel risk probability is 1.70×10-3 in the threats range.
