摘要

提出了一个新的次塑性模型并用试验作了初步验证，建议用异步交叉迭代显式差分有限元求解固液耦合动力弹塑性问题。利用次塑性模型以及动力固结有限元计算程序，对一简单饱和砂土地基的动力弹塑性响应进行了分析，取得了合理的结果。

Abstract

A new hypoplasticity model is proposed and verified using tests. An asynchronous staggered iteration FEM method with explicit difference scheme is suggested to solve solid-liquid coupling dynamic elastoplastic problem. The hypoplasticity model is implemented in Biot dynamic consolidation finite element program. The solid-liquid coupling dynamic elastoplastic response of a saturated sand foundation is analyzed; and reasonable results are achieved.
