| 摘 要： | 本文基于非曼辛准则提出了两个土动弹塑性模型。在模型中引进了两个模型参数ｎ１，ｎ２，改进了土弹塑性模型的构成方法。给出了在等幅动荷载作用下及非规则荷载作用下这两个参数的确定方法。将本文提出的两个土动弹塑性模型用于土层弹塑性地震反应分析，并与通常采用的等效线性模型的地震反应分析结果做了比较。

| Abstract: | ln this paper. two dynamic elastic-plastic model. are proposed based on non-Mansing's rule. Two parameters n1 and n2 are introduced into the models. The methods fordetermining the two parameten in case of uniform cyclic loading and irregular cyclic loading are presented. The two dynamic elastic- plastic models are used for response analysis of soil layers to earthquakes. and the results are compared with those from the analysis of equivalent linear model. It is found out that the former is mnre reasonable than the latter. |
