Abstract

Abstract

The eastern Tibet section of Sichuan-Tibet Highway is always suffered by unstable slopes even after years of repeated governance. In order to solve this urgent problem, a good knowledge of all slope data and slope treatment status of this area must be obtained. Totally 204 slopes along the Highway have been investigated in detail for three years. The present situation of slope treatment was counted, and its characteristics were analyzed distinguish by soil and rock landslides. Based upon data, factors causing slope instability were analyzed, and slope stability evaluation model was established using random forest method. The importance of influencing factors for slope stability and stability of all slopes were calculated by the model, and the model test showed that the accuracy was over 94.44%. The study results of this article could be used in the engineering management of highway works department. Also, suggestions are proposed on the management of highway slope based on the field investigation.
