| 摘 要： | 在上海软土各向同性破坏准则的基础上，引入各向异性参数，对上海粘 中向异性弹塑性模型的建立进行研究和探讨，并对模型中的各项参数进行了确定。计算结果表明，在确定土体应力－应变关系时，不仅应考虑土的弹塑性，同时还应考虑到土的各向异性。

| Abstract: | Based on the isotropic failure criterion, an anisompic elasto-plastic medel for Shanghai soft soil is presented in this paper. The model can consider soil anisotropy and elasto-plastic behavior at the sam time. Methods for determining the model paramters are also presented. The calculated restilts by the proposed anisompic elasto-plasticmodel agree quite well with the tested results. |
