应变率对高压下粒状土稳定性影响的实验研究表明，对失稳线的位置没有明显影响。然而，在不排水三轴压缩试验的偏应力，有效应力路径，有效应力摩擦角，孔隙水压力显着影响的应变率的变化。排水三轴压缩试验过程中的应变率效应也被提出，但似乎并不像不排水试验那样显著。
An experimental study of the effect of strain rate on the stability of granular soils at high pressures has shown that there is no apparent effect on the location of the instability line. However, during undrained triaxial compression tests the deviator stress, effective stress path, effective stress friction angle, and pore pressures are significantly affected by changes in strain rate. Strain rate effects during drained triaxial compression tests are also presented, but do not appear to be as significant as in undrained tests.
