摘要
用无网格伽辽金法(EFGM)按平面应变问题对含两个圆形孔洞的岩盐路基进行稳定性分析,给出了针对不同孔洞埋深的临界载荷.数值结果表明,EFGM对于解决含两个孔洞的应力集中问题是有效且灵活的.
The stability ofa rock-sah roadbed with two circular cavities is analyzed as a planar strain stress problem with the element-free Galerkin method(EFGM). The critical loads were presented for the cavities at different depth. The numerical results show that EFGM is not only effective but also flexible for a stress intensity problem with two cavities.
