摘要

在总结结构性土压缩特点的基础上，以岩土破损力学理论中的弹塑性元（软弱带）为参照状态，通过引入一个可以表征土体结构影响的结构状态参数，建立了结构性土压缩曲线的数学表达式。通过结构性土的单轴压缩试验和等向压缩试验，验证了建议的模型可以较好地模拟结构性土的压缩变形特性。由于建议的表达式可以反映结构性土的压缩曲线在 - 坐标中的非线性，对于结构性土的沉降计算有一定的理论意义。

Abstract

The compression properties of naturally and artificially structured soils under one-dimensional compression or isotropic compression are described comprehensively. The reconstituted soil samples or the elastoplastic element of breakage mechanics for geological materials are regarded as the reference state; then by introducing a structured state parameter ? reflecting the influence of soil structure

the formula of the compression curve of structured soils is established. Finally

the proposed model has been verified for two different structured soils under confining stress conditions and under isotropic stress conditions respectively; and it is seen that the proposal describes well the behavior of these two soils. The formula suggested reflecting the nonlinearity of compression curve for structured soils has some theoretical meaning for the settlement calculation of structured soils.
