摘要

通过对天津市欠固结海积软土进行的大量试验，研究了土的结构性和弹塑性变形本构关系两个方面的问题。首次引入结构强度系数，建立了微结构定量参数与力学参数之间的关系，并提出一种综合考虑结构性影响的应力应变关系模型，为海积软土的结构性模型研究及实际应用提供了一条新的途径。

Abstract

Two problems of Tianjin pre-consolidation marine soft clay have been studied through large numbers of tests. One is the structure of soil; the other is elastoplastic model. The structural strength coefficient is led into for the first time

the relationship between microstructural quantitative parameters and mechanical parameters is established. A new kind of constitutive model is proposed to estimate the stress-strain relationship with the changes of structure and so as to offer a new channel for the structural model research and actual application of marine soft clay.
