However it was found that this theory was not suitable for sand modeling due to the ignorance of internal state variable of materials in the definition of dilatancy equation.

最新的研究表明：由于应力剪胀理论中忽略了土体内部状态参量对剪胀的影响，而使得该理论应用于砂土时发生了困难。

The so called state-dependent dilatancy theory was suggested and applied in sand modeling.

本文就砂土的状态及其描述、剪胀理论的发展、砂土本构模拟等方面进行介绍。

The volumetric strain due to stress-dilatancy of sand is found to be composed of a reversible dilatancy component and an irreversible dilatancy component.

基于对较高精度的砂土扭剪试验成果的分析，表明砂土的剪胀是由一个完全可逆的体应变分量和一个不可逆的体应变分量构成的。

The deformation of slope caused by change of ground water level was investigated by adopting a fully coupled procedure and the state-dependent dilatant sand model.
