摘要： 以能量守恒原理为主线，在现有简化版砂土剪胀方程(比如Camclay、修正Camclay和Rowe等的剪胀方程)的基础上，通过对各向同性砂土引入状态参数、对横观各向同性砂土同时引入状态参数和各向异性状态参数，逐步展开较为复杂的砂土剪胀方程的综述.最后指出了初始组构张量及其在后期受荷变形过程中该组构张量的逐步演化对砂土剪胀方程的影响是今后研究的方向.

关键词: 剪胀方程;塑性势;状态参数;各向同性;横观各向同性

Abstract: With the energy conservation as the clue, it reviewed some more complicated sand dilatancy equations, which are obtained through incorporating state parameter for homogeneous sand, and the state parameter and anisotropic state variable for transverse homogeneous sand, based on some simple version sand dilatancy equations such as Camclays, modified Camclays, and Rowes et al. It points out that initial fabric tensor and loadinginduced fabric tensor incorporated into sand dilatancy equation will be the main research aim in the future.

Key words: dilatancy equation; plastic potential; state parameter; homogeneity; transverse homogeneity
