| Abstract: | In relation to complexity of slope stability, the rock cutting high slope engineering in the K79+720~K80+080 Section of Urumqi-Bayinggou Highway of Xinjiang Provincial Road 101 was studied by multiple methods on the basis of the analysis of geological background and the environmental conditions. By rock mass classification, stereographic projection method, limit equilibrium method and finite element method (FEM), the comprehensive evaluation and integral analysis were carried out with optimized design of slope angle for excavation. The generalized conclusion is adopted by designers and builders. |
