摘　　要：采用离散元程序UDEC对某铅锌矿山节理岩体采场稳定性进行数值分析,模拟了片理结构岩体采场破坏过程及相应力学状态,同时提出了控制片理结构岩体采场变形和破坏的措施,取得了良好的效果,同时也证实了UDEC是一种很好的数值分析软件,特别适用于模拟节理岩体的变形问题研究.This paper studies the numerical simulat ion on the stability of jointed rock mass with schistosity structure in a lead-zinc mining by universal distinct element code（UDEC）.A failure process and stress-state of adjacent rock mass was obtained by proposing the plan for controlling the deformation and failure for jointed rock mass with schistosity structure.UDEC is confirmed to be a good numerical analysis software,especially suitable for simulation of the deformation of jointed rock mass.
