摘要
依据岩土工程学理论,确定了隧道安全岩柱的影响因素,分析了隧道(巷道)开挖围岩二次应力场分布规律、采空区承压水对隧道安全防水岩柱的影响机理及采空区工作面矿压显现规律、得出了隧道安全岩柱稳定性的评价计算方法。研究成果对采空区下铁路隧道的安全稳定性分析具有指导现实意义。
According to geotechnical engineering theories, the study determines the influential factors of tunnel security pillar, analyzes induced stress field distribution among the surrounding rocks of tunnels, influential mechanism of confined aquifer in abandoned areas to tunnel security pillars and strata behaviors, and concludes the evaluation method of security pillar stability. The study is significant in practice for stability analysis in similar situations.
