Abstract Research purposes: The slope deformable body of ZheguMountain was a potentially large -sized sliding deformable body and itwas in the creep deformation stage. The big landslidewould probably happen under the effect of heavy rain or the external disturbance to interrupt the traffic of the NationalHighway 317. This paper studies and analyzes the reasons for formation of the slope deformable body and offers themeasures to be taken for treating the slope deformable body to ensure the entire stability of the slope deformable body and smooth traffic ofNational Highway 317.
Research conclusions:Through the analyses of the reasons for formation of the slope deformable body and the characteristics ofslope deformable body in the creep deformation stage, the proposalwasmade the integral treatment had to be conducted. Namely, the slide -resistantpile was adopted for reinforcing the down part of the slope deformable body, the anchor-framed framework was adopted for reinforcing the steep surface and the deep foundation slide –resistant key was adopted for reinforcing the middle partof slope deformable body. After conducting these treatments,the slope deformable bodywas stable entirely andwell stood theWenchuan Earthquake and heavy rain.
