Based on the hypothesis of equivalent strain energy, the constitutive relation of anchoring discontinuous joint rock mass under the state of complex stress and damage evolution equation are established, and applies it to the stability analysis of high slopes of Three Gorges Flight Lock.

Study on bolted discontinuous rock mass by composite element method;

It is of great significance to study the coalescence mechanism of splitting failure of rock masses with intermittent joints under compression.

A 3D constitutive laws and the damage evolutions of bolted discontinuous jointed rock mass are used to evaluate the stability and deformability of the surrounding rock mass during excavation and supporting.
