摘要
初始地应力是地下工程围岩稳定与支护结构设计的一个基本参数。介绍了地应力计算原理 ,并根据矿井实测地应力资料 ,分析了初始地应力场与巷道布置及巷道破坏形式的关系。为今后选择巷道掘进方向和改进巷道支护方案提供了依据。
In situ stress is one of the basic parameters f or the stability of surrounding rock and the design of support structure.The algorith m of in situ stress is presented in detail.Based on the site measurement res ults ,the correlations of the in situ stress field with the layout of tunnel and its failure mode are analyzed in this area,which are important to the determination of the advancement direction of roadway and the supporting scheme. underground <
