摘要
Abstract
In accordance with the status that multi-groups of pre-stressed anchorages are arranged there inside of a rock slope, but no enough knowledge on the parameters of the grouting slurry around the pre-stressed anchors therein is available, a method to evaluate the strengthening effect of the group anchorage of rock slope is put forward herein, I. E. the pre-stressed anchor is simulated by TRUSS element of ABAQUS finite element software on the basis of the simulation of the rock slope with Mohr-Coulomb constitutive model, and the strengthening effect from the group anchorage on rock slope is evaluated through numerical calculation with the strength reduction method. The study result shows that the safety factor of rock slope cannot be significantly increased by the group anchorage, but the development and the possible failure process of the plastic zone of rock slope can also be alleviated, if compared with those un-strengthened ones. Therefore, this method can be applied to the comparative optimization made on all the kinds of group anchorages for strengthening rock slope in the engineering practice concerned.关键词
