Study of Guizhou Province Guanling Daz-Hai Landslide Instability Process under the Rainstorm

Abstract:

Guizhou province GuanLing Dazhai high speed and long distance landslide in the June 28 of is one of the typical landslides that related to rainstorm in 2010. The strength of Dazhai landslide which is given priority to with mudstone decreased rapidly under the softening action of the heavy rain. Hydrostatic pressure of landslide rear fissure and buoyancy of sliding surface for the stability of the landslide decline has played a significant impact. Combined with strength reduction method and using 3DEC for simulating Dazhai landslide. Landslide safety coefficient before and after rainstorm are obtained and analyses the instability of the landslide.
