摘　　要：为了解决数值模拟计算中复杂建模和单元剖分等前处理难度大的问题,采用三维地学模拟与数值模拟耦合的方法,研究了Surpac和Phase2耦合采空区围岩稳定性模拟。结合某矿山复杂空区群的实际情况,应用Surpac建立了矿山地学三维模型,将数据转换后导入Phase2软件构建了数值分析模型,进行了数值模拟计算,并根据模拟计算结果对采空区的围岩稳定性进行了分析。结果表明,采用数据转换方法将Surpac和Phase2两者的优势充分结合起来,为岩土工程的稳定性数值模拟研究提供了一条新的有效途径。The paper uses the coupling method of three-dimensional geoscience modeling （3DGM） and numerical simulation to resolve the problem of complex numerical modeling successfully. The geological model of a mine is constructed by using the Surpac software according to the cavity group situation of the mine, and then transforms the Surpac modeling date into Phase^2 to build the numerical simulation model; thirdly, the simulation calculation is carried out. Finally, the stability of cavities surrounding rock mass is analyzed according to the simulation calculation results. It is proved that the combination of the advantages of Surpac and Phase^2 by transforms method provides a new and effective way for numerical simulation study on the stability of rock engineering.
