In Situ Shear Experimental Study on Loess Landslide
On the basis of analysis on the geological environment of highway loess landslide, three in-situ loess samples,500mm×600mm×600mm, were cut on the shear crack of landslide. The residual shear experiment of soil samples were accomplished in native state and saturated case. Compared with the residual cohesive force and residual internal friction angle of slide face soil in native state by indoor shear experiment, that of landslide shear crack soil in saturated state by in situ shear experiment is grater with the degree of 12.25% and 29.38%.The reason of difference between two experimental methods is proposed. It shows that in situ shear experiment is very important to the landslide stability analysis and the optimization of landslide engineering treating, specially to the creep landslide.
