摘要

三峡右岸地下电站厂房围岩断续节理发育

为了限制岩体的变形破坏

需采用锚杆(索)进行加固。如何正确估价开挖后洞室围岩节理损伤演化扩展和判断其稳定性是十分重要的。采用损伤力学方法得到的加锚节理裂隙岩体的本构关系及其损伤演化方程来评价此类岩体稳定性和变形行为。

Abstract

The surrounding rock mass of underground powerhouse in the rig ht bank of the Three Gorges is cut by well-developed joints. The constitutive law and the damage evolution equation of the anchored discontinuous jointed rock mass are set up by damage mechanics

and they are used to evaluate the stability and deformability of the surrounding rock mass during excavation and supporting.
