摘要层状岩体拥有明显的层理面、微裂隙等微观构造，加载受力后呈现出较为复杂的各向异性强度特征。空间结构的各向异性特征是内因，可以利用微结构张量–应力张量的联合不变量进行刻画。附加荷载诱发岩体破坏是外因，在外部荷载作用下，岩体内部存在潜在破坏面，潜在破坏面所在位置的固有强度决定了破坏强度。SMP准则建立了应力加载方向与材料内成对存在的潜在破坏面之间的位置关系。基于SMP准则，综合考虑固有强度的变化规律和破坏面的位置，可以构建层状岩体的各向异性强度准则(ASMP准则)。该准则仅新增2个可由试验直接测得的强度值。已有试验数据和ASMP准则计算结果对比表明，ASMP准则可以较好地预测常规三轴、真三轴压缩等复杂应力路径下多类层状岩体的破坏强度和破坏面位置。

Abstract：Layered rock mass has distinct microstructures such as bedding planes and microcracks，and exhibits complex anisotropic strength characteristics after being loaded. The anisotropic characteristic of spatial structure is the internal factor，which can be characterized by joint invariants of microstructure tensor and stress tensor，and additional load inducing the rock mass failure is the external factor. There are potential failure planes inside the rock mass under external loads，and the failure strength is determined by inherent strength of the location of the potential failure planes. The SMP criterion explains the positional relationship between the stress loading direction and the paired potential failure planes in the material. The anisotropic strength criterion(ASMP criterion) for layered rock mass is constructed based on the SMP criterion，considering the variation of inherent strength as well as the location of failure plane. Compared with the SMP criterion，there are only two newly added strength values measured by experiments directly in the ASMP criterion. Comparing the existing experimental data and the calculation results of ASMP criterion，it is found that ASMP criterion can effectively predict the failure strength and plane position in multiple types of layered rock masses under complex stress paths，including conventional triaxial and true triaxial compression.
