摘要

用无网格伽辽金法计算了孔洞边缘危险点的应力。对含单个孔洞岩盐路基的稳定性进行了分析，给出了针对不同孔洞埋深的临界载荷。数值结果表明，EFGM对于解决含有单个孔洞的应力集中问题，是有效且灵活的。

Abstract

The stresses of the most dangerous point on the edge of a cavity are calculated by using of element free Galerkin method(EFGM). The stability of rock-salt roadbed with single cavity is analyzed. The critical loads are presented for different depths of cavity

The numerical result shows that EFGM is not only effective

but also flexible for the stress intensity problem with one cavity.
