摘要

应用一个高度非线性的三维各向异性粘弹塑性（EVP）模型及有限元法

对一水泥土桩（CDM）加固海洋土的复合地基进行数值模拟。海洋软粘土的渐进变形采用粘弹塑性模型来模拟

水泥土桩破坏前后的应力-应变关系采用一个双曲线模型来模拟

提出了一个简单且非常实用的数值分析方法来解决水泥土桩碎裂软化的数值模拟问题。将数值模拟结果与实测数据进行了比较

二者吻合较好。

Abstract

Finite element analysis incorporated with a highly nonlinear 3-D anisotropic elastic viscoplastic （EVP） model is performed for a deep cement mixing （DCM） column improved marine clay foundation. The 3-D anisotropic EVP model is used for the unimproved soft marine clay （MC）; and a hyperbolic model is used for DCM soil column before and after local failure. A simple yet workable method is presented for finite element solution to local failure induced strain softening of DCM soil column. The measured and predicted settlements and pore water pressures are compared

interpreted and discussed. Numerical results are in good agreement with measured data.
