| 摘 要： | 地应力环境与围岩力学属性是隧道工程中引发岩爆的两大决定性因素。为了研究黑石岭隧道开挖过程中围岩岩爆灾害的潜在威胁及其表现规律,通过对岩爆里程段的现场采样、运用Kaiser效应法测量原岩应力和室内岩石力学实验,探讨了工程区内白云岩的岩性特征及其破坏规律,并基于强度理论和冲击能指标分析了发生岩爆的可能性及其发生方式。分析得知,该工程区内岩爆的潜在威胁较大,尤其是测点1和测点2处发生强岩爆的可能性最大,须在工程开挖过程中加强防治。

| Abstract: | In-situ stress and rock mechanical properties are two decisive factors of rockburst caused by underground tunnel excavation.In order to research the potential threat and the law of rockburst in Heishiling Tunnel excavation process,based on scene sampling in rockburst area,in-situ stress measurement by Kaiser effect method and indoor rock mechanical experiment,we investigated the mechanical properties and failure law of dolomite rock in project area.Then,based on the strength theory and the impacting energy ... |
