摘要
众所周知，水平应力的大小和方向对巷道顶板稳定性起着决定性的作用。文章分析了各种巷道布置情况下，水平应力与围岩破坏的关系，尤其对三维应力状态的深入分析，对锚杆支护设计和优化巷道布置均有参考价值。
Abstract The magnitude and direction of horizontal stress has an essential influence on the stability of roadways.This paper presents an analysis on the relationship between rock failure and horizontal stress with various roadway layouts.Results of this analysis,especially those with three dimensional stress,are very helpful in rockbolting design and optimization of roadway layout.
