材料的库仑破坏准则通常隐含地应用于破坏面上的应力分量。在这项研究中，它试图应用库仑准则不仅对故障平面，而且对一般平面，其中有各种方向相对于主应力分量在故障。用该模型对不同岩土材料的三维破坏条件进行了模拟，包括干净砂土、饱和和非饱和细土、胶结砂土和砂岩。提出库仑破坏准则的平面方向与摩擦力、粘聚力一样，也是材料的强度参数之一。
The Coulomb's failure criterion for materials is commonly and implicitly applied to the stress components on failure plane. In this study, it was attempted to apply the Coulomb's criterion not only to the failure plane but also to general planes, which have various directions relative to the principal stress components at failure. Three dimensional failure conditions of various geomaterials including clean sands, saturated and unsaturated fine soils, cemented sands and a sandstone were examined and simulated by the newly proposed model. It is suggested that the direction of the plane for the Coulomb's failure criterion is one of the strength parameters the materials as well as its friction and cohesion.
