摘要
软岩巷道支护一直是一个难以彻底解决的问题,利用计算机数值模拟分析方法,对在软岩巷道中影响锚杆支护效果的预应力、支护方式、锚杆长度及位置等方面内容进行了计算机模拟对比分析,得出使用锚杆支护时适合软岩掘进巷道相关参数的选择方法,从而利用分析结果指导工程实践。
Soft rock roadway supporting engineering is an ever existing difficult problem. By the method of numerical simulation with computer,many factors affecting the effects of supporting in soft roadway were simulated and analysed,including pre-stress,supporting method,length of rock bolt and the placement of the bolt. Finally,the determination methods on relevant parameters of bolt supporting in soft rock roadway was proposed,and results of the analysis can be used to guide engineering practice.
