二级边坡稳定性的三维分析
3D stability analysis of two-stage slope
摘要
Abstract
This paper constructed a three-dimensional failure mechanism. The analytical solution of the slope height was then deduced on the basis of linear Mohr-Coulomb failure criterion and limit analysis. By virtue of ex-haustion method, the numerical results of the stability factor of two-stage slope were derived as well. Moreover, by comparing with the results of Michalowski, the validity of the solution was demonstrated. The results show that:the stability factor of slope not only relates to inclination angle and internal frictional angle, but also relates to depth coefficient and depth-width ratio.关键词
