Based on the test results of sand, mechanics of internal parameters ( plastic volumetric strain and plastic deviator strain) depending on stress path is explained. General equation expressing hardening parameter independent of stress path is proposed.

在分析砂土试验结果的基础上，揭示了基本硬化内参量（塑性体积应变、塑性剪应变）变化的应力路径相关性，提出了应力路径无关硬化参量的一般表达式。

The force of instantaneous steady seepage results in the vertical stretching of the foundation under geomembrane and the lateral compression, which make the foundation in the state of pure shear stress with small volumetric compressive deformation, thus, the foundation cannot be reinforced effectively.

瞬时稳定渗流体力使膜下地基竖向拉伸、侧向受压，接近纯剪切应力状态，体积压缩变形较小，难以有效地加固地基。
