Adopting the method of structural mechanics and UNWEDGE program
stability of top staff tor a large underground cavern under single discontinuity
groups of discontinuities and fragmentized rock mass is discussed so as to obtain the critical stable thic1:ness and the feature of potentially instable blocks
which can be beneficial to guiding excavation and timbering.
