| 摘 要： | 在三维各向异性弹塑性本构关系基础上，求解不排水条件和破坏条件，导出各种不同试验条件下K0团结粘土的各向异性不排水剪强度表达式。对常规超固结比定义下的不排水剪强度进行研究，将理论计算结果与试验结果进行比较，验证所提理论的合理性。

| Abstract: | Based on the 3-dimensional anisotropic elasto-plastic constitutive relationship, the undrained and failure conditions are obtained, the anisotropic undrained strength of K0 -consolidated clays under various testing conditions are formulated. Then study on undrained strength with conventional definition of overconsolidation ratio is made. Finally, the theoretical results are compared with the measured ones in order to verify the validity of the present theory. |
