摘要

应用耦合损伤的滑移线法，求解平面应变条件下的极限荷载问题，推导出考虑各向异性损伤的平面应变问题应力场的滑移线解，针对平顶钝角楔体极限荷载的滑移线场进行了详细推导，绘出滑移线场图，推导出极限荷载的公式，分析了各向异性损伤对浅基础极限荷载的影响，即损伤对地基承载力系数Nq影响很大；损伤越大，地基承载力系数Nq值越小，且随着D1，D2的增加，Nq越接近最小值。

Abstract

The solution of slip line for evaluating the ultimate load influenced by anisotropic damage is derived under plane strain condition. The field of slip line is drawn. Finally

the influence of anisotropic damage on bearing capacity of shallow foundation is studied. With isotropic consolidation clay

bearing capacity factor Nq reduces with the increase in damage accumulation

until it may be a minimum value.
