摘要:
根据三维无网格Galerkin方法研究了无限大立方体中球形孔洞应力集中问题. 分别采用最大拉应力准则、格里菲斯(Griffith)和摩尔-库伦准则作为稳定性判据,数值模拟了含球形孔洞岩盐路基稳定性问题,给出了不同孔洞埋深下岩盐路基的临界载荷.
关键词: 无网格方法;球形孔洞;岩盐路基;临界载荷
Abstract:
The stress concentration of a spherical cavity in an infinite cube was studied by the three-dimensional elementfree Galerkin method. The maximal tensile stress criterion, Griffith criterion and Moore-coulomb criterion was respectively taken as the stability criterion. The stability of a rock salt roadbed with a spherical cavity was numerically simulated. The critical load of a rock salt roadbed with different cavity depth was given.
Key words: element free galerkin method; spherical cavity; rock salt roadbed; critical load
