| Rock slope stability analysis is an engineering problem.There are many methods for rock slope analysis.However,due to the complexity of rock slope,there are still some problems in the multi-method analysis.A lot of analyses of the nature of the isotropic are carried out in previous studies,while this paper adopts transverse isotropy in the analysis of rock slope stability.The main content is as follows: firstly,considering the overall situation of rock,the reduction of rock strength is conducted in light of the Hoek-Brown strength criterion,and the fitting of the rock strength parameters of transversely isotropic is carried out;two kinds of rock slopes are analyzed with the application of limit equilibrium method(Bishop method and Spencer method),it is found that the safety coefficient of transversely isotropic rock slope correction shear strength is 10% lower than that of the isotropic rock edge;based on ABAQUS finite element software,two types of slopes are analyzed with strength reduction,it is found that the safety coefficient of transversely isotropic rock slope is 10% lower than that of isotropic rock slope,and the effect of transversely isotropic on the rock slope is obvious;the effects of the joint on the rock slope are also studied,the result is that the joint has a great impact on the rock failure mode of jointed slope;finally,the engineering practice Ruchen highway is analyzed to,prove the feasibility and prospect of the adoption of slope with transversely isotropic in practical engineering.Rock slope analysis is influenced by many factors,such as the uncertainty of the rock material.This paper analyze the rock slope through the optimization of the model,so there are many shortcomings,but as the influence of isotropic on rock slope is large,the rock transversely isotropic should be considered in the practical analysis. |
