摘　　要：岩体隧道中结构面的存在会极大地影响岩体的力学性质。根据经典块体理论和蒙特-卡罗模拟方法,采用面向对象的C++语言为主要工具,实现了岩体结构面分组的自动化,然后在此基础上完成了岩体隧道中随机性关键块体的搜索,并应用计算机图形显示技术,展示了岩体结构和随机块体的三维模拟方法。Existance of structural surface in rock mass tunnel will extremely affect mchanical propertie of rock mass. By classical block theory and Monte - Calo simulating method, taking C ＋ ＋ language as major means is made, the auto mation of rock mass structural surfee grouping is also carried out. On this basis, the search stochastic critical block is accomplished, and the techniques of computors graphical display are applied, which reveal 3D simulation methods for rock mass structure and stochastic block.
