主剪应力
Coincidence between the orientation of normal contact force anisotropy and the direction of the major principal stress has been observed during all stages of shear loading.
整个加荷过程中,剪切带内大主应力的偏转方向与法向接触力各向异性的主方向保持了良好的一致性。
The more is principal stress deviator peak, the more possible is to emerge negative pore water pressure and to show more shear dilatation with high dry density.
干密度越大,主应力差峰值越大,表现出较大的剪胀性,孔隙水压力易出现负孔隙水压力;
