摘要
在各向异性弹粘塑性本构关系基础上，推导考虑粘性的各向异性不排水剪强度表达式，探讨剪切速率（或破坏时间）与不排农剪强度之间的关系，并从理论上解释各向异性不排农剪强度的速率相关性，最后将理论计算值与试验结果进行比较，验证理论的合理性.
Based on the elasto-viscoplastic constitutive relationship, the formulations of anisotropic undrained strength considering the viscial effect are presented and the effects of shearing rate on undrained strength are discussed.Then the anisotropy in rate-dependency of undrained strength is interpreted theoretically. Finally, the computed results are compared with the measured ones so as to verify the validity of the present theory.
