| 摘 要： | 无网格伽辽金法(EFGM)可脱离单元的概念，特别适合岩体裂纹面的接触摩擦分析。基于EFGM，在裂纹面引入罚参数，通过迭代计算，得到裂纹面真实的应力状态，从而模拟闭合裂纹的粘接、滑移和张开行为，数值结果表明该方法是合理可行的.

| Abstract: | Element-free Galerkin method (EFGM) is especially suitable for analysis of the frictional contact problems of rock structures because no element connectivity is needed. Based on EFGM, the penalty parameters are introduced on the cracks. Through the iteration process, the true stress states can be obtained and the contact criterion is applied to determine that the interfaces are open or closed. Numerical examples show that this method is effective. |
