摘要
本文在提出了非均质非线性各向异性岩土材料三维破坏准则的基础上,导出了与该准则相关联的流动法则,进而建立了平面变形条件下的强度理论。这一准则形式是Mohr-Coulomb准则对各向异性材料的推广,对解决复杂介质变形与稳定问题有一定的实用价值。岩土力学与塑性力学中广泛采用的Mohr准则、Coulomb准则、Hill准则、Tresca准则均被概括为本文准则的特例。
Strength theory for complex rocks and soils under the condition of plane strain is given. Three dimensional failure criterion of nonhomogeneous nonlinear anisotropic rocks and soils is used. The associated rules of flow are derived from the criterion. Plain strength criteria are established. These criteria are generalization of the Mohr-Coulomb criteria in anisotropic materials. Many classical criteria may be obtained through simplifying the criteria proposed. The strength theory presented is significant to engineering design in complex rocks and soils.
