中文摘要：
分别使用Goodman节理单元模型和所推出的等效模型，对具有一组和二组节理的受力岩体进行了有限元计算。最后应用所推出的等效模型列一个在节理岩体中的洞室开挖进行了数值模拟，看到试验与计算结果大致符合，显示了所推出的等效模型是有效的。
英文摘要：
From the equivalent model of rockmass with one set of joint in local coordinate system suggested by Goodman et al, through the coordinate transformation the equivalent model of rockmass with multi-set joint in global coordinate system was obtained. Using the Goodman＇s joint element model and the derived equivalent model respectively, 2D FEM analyses were made for the rockmasses with one and two sets of joint under some condition of loading. Finally a numerical simulation for an opening excavation in a jointed rockmass was carded out by applying the derived equivalent model. It could be seen that the results of test and computation were roughly identical, so the effectiveness of the derived equivalent model was shown.
