Modeling calculation and optimization scheme of road side landslide stability in Dongqu Highway
In order to solve the complicated problem that the shear strength of landslide sliding zone is difficult to be accurately selected in the process of analyzing the stability of high landslide on the side of the road,this paper takes the actual engineering project as an example,and uses the implicit solution of the fold-line transfer coefficient method to carry out back analysis calculation,engineering analogy and field shear test under specific conditions to compare and determine the shear strength index of the sliding zone.Based on the obtained shear strength index,the present stability of landslide and the stability after checking the support are analyzed,and the feasible support treatment scheme is put forward.Finally,the selection of shear strength of sliding zone is verified by the current situation of slope after support,which provides a reliable reference for subsequent similar projects.
