摘要

为了探索结构性黏土的一维压缩特性模拟方法，广泛调查研究了中国12种典型的结构性黏土的一维压缩试验，分析比较了这些黏土的原状土样和重塑土样的一维压缩试验结果，通过引入“结构比”变量并建立其破坏规律，提出了一个简单的可以描述结构性黏土一维压缩特性的模拟方法，并利用扰动状态概念推广此方法至扰动状态模型。最后，应用此模型模拟了结构性黏土的一维压缩实验，验证了此模拟方法的适用性。

Abstract

In order to investigate the 1D (one dimensional) compression behavior for China structured clays in a simple way

the experimental results on intact and reconstituted clay samples for 12 typical China natural clays located from south to north in China were analyzed. Based on these

a modeling method for destructuration behavior was proposed by introducing the bonding ratio and furthermore extended to disturbance soil model by using disturbance state concept. The proposed model was then validated by simulating 1D compression tests of various natural clays.
