摘要
采用结构力学方法和块体稳定性分析程序UNWFDGE分析了溪洛渡水电站大型地下洞室中错动带单条发育、结构面成组发育和结构面集中发育呈碎裂岩体三种情况下的围岩稳定性,得出了错动带出露的临界稳定厚度和潜在不稳定块体的特征,为支护处理提供了重要的理论依据。
Adopting the method of structural mechanics and UNWEDGE program, stability of top slab for a large underground cavern under single discontinuity, groups of discontinuities and fragmentized rock mass is discussed so as to obtain the critical stable thickness and the feature of potentially instable blocks, which can be beneficial to guiding excavation and timbering.
