摘要

本文研究了非粘性部分饱和土在三轴压缩下的不排水响应模型。所提出的模型基于描述剪切过程中非粘性土破坏前响应的增量方程。Sawicki开发的原始模型在考虑孔隙流体压缩性的情况下进行了修改。该控制方程使模拟不排水条件下的有效应力路径成为可能。将数值结果与实验数据进行了比较。

Modelling of the Response of Partially Saturated Non-cohesive Soil Subjected to Undrained Loading

Abstract The paper deals with the modelling of the undrained response of non-cohesive partially saturated soils subjected to triaxial compression. The model proposed is based on an incremental equation describing the pre-failure response of non-cohesive soils during shearing. The original model, developed by Sawicki, was modified by taking into account pore fluid compressibility. The governing equation makes it possible to simulate effective stress paths under undrained conditions. Numerical results are compared with experimental data.
