Taking the underground excavation of Xiluodu Hydroelectric Power Station as an example, the rock mass structure is classified based on research on distribution of fractures Adopting the structural mechanics method and UNWEDGE program, the hat stability under single fracture, groups of fractures and fragmentized rock mass is discussed in this paper to obtain the critical stable thickness and the feature of potentially instable blocks, which can be a beneficial guidance to excavation and timbering.
文章以溪洛渡水电站地下工程为例,根据断裂分布情况的研究对岩体进行分类。采用结构力学方法和UNWEDGE程序讨论了单个裂隙,成组裂隙和岩石碎块情况下顶部的稳定性来得到临界稳定厚度和可能失稳岩块的特点,可以为挖掘和支撑工作提供有益的指导。

The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.
