| Abstract: | 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. |
