摘要/Abstract

摘要： 锚杆支护的一般作用原理是提高围岩各向力的平衡程度。锚杆支护在特殊条件下的作用原理是对围岩吊挂固定。对比使用锚杆前后围岩基本力学参数变化，可以看到锚杆调整围岩应力平衡的作用，远大于吊挂固定围岩的作用，围岩应力分布状况是锚杆设计安装的依据。

关键词: 锚杆支护, 吊挂固定, 围岩应力平衡

Abstract: The normal supporting principle of rockbolt is improving the balance of stresses of surrounding rock mass. The supporting principle of rockbolt under special construction situation is reinforcing the surrounding rock mass. The balance improving effect is larger than the reinforcing effect on surrounding rock mass by means of comparing the basic mechanical parameters of rock before and after rockbolt using. The distribution of rock stress is the basis of design and installation of rockbolt.

Key words: rockbolt support, suspended rockbolt reinforcement, rock stress balance
