本文采用塑性应变分量的分部屈服概念,提出了适用于增量法计算的分部屈服加载准则;并且参照非线性变形理论,提出了新的土体弹塑性模型。本文属于理论探讨,有关计算成果及其分析将在另文发表。
In this paper, the concept of partial yield of plastic strain component is adopted, and the criterion for the yield load of subsections is given for the incremental method calculation. A new soil elastic-plastic model is proposed by referring to nonlinear deformation theory. This article is a theoretical discussion. The calculation results and their analysis will be published in another article.
