利用 Unwedge 程序分析地下水位对硐室块体稳定性的影响，进行考虑地下水压力和不考虑地下水压力2种工况计算，得出2种工况下块体的安全系数；对块体在不同水位高度和不同结构面受水压力工况下进行计算，得出安全系数随水位高度变化的曲线。通过数据对比得出，地下水压力的存在能够大大降低块体的安全系数，并且随水位的增加而非线性降低，从而证明利用 Un-wedge 程序进行块体稳定性分析是合理而必要的。

The effect of groundwater level on mine cavern block stability is analyzed by Unwedge.Two methods are used,one considering the groundwater pressure and the other not.The safety factors of blocks are obtained respec-tively.Besides,the calculation is carried out under different groundwater levels and different water pressure against structure surfaces.The curves are obtained,which show the change trend of the safety factor according to the height change of water level.The data comparison shows that groundwater pressure can greatly reduce the safety factor of blocks,and may also decrease nonlinear with the increase of water level.The results prove that Unwedge is a reasona-ble and necessary tool to analyze the cavern block stability.
