非饱和土的抗剪强度是当前土力学中研究的热点也是难点,由于非饱和土强度的影响因素较为复杂,因此如何准确地确定非饱和土强度较为困难,目前研究的方法也较多。非饱和土与饱和土强度的本质区别在于含水量的不同,将饱和土的抗剪强度公式运用于非饱和土计算当中对确定非饱和土的抗剪强度有一定的现实意义。本文用含水量确定非饱和土抗剪强度计算公式中的各参数,从而确定非饱和土的强度,对现实工程具有一定的指导意义。
The shear strength of unsaturated soil is hot and difficult in current soil mechanics research. Because the influencing factors of unsaturated soil strength are complex, how to accurately determine the strength of unsaturated soil is more difficult, and there are many methods studied so far. The essential difference between the strength of unsaturated soil and saturated soil is the difference of water content. It is of practical significance to determine the shear strength of unsaturated soil by applying the formula of shear strength of saturated soil to unsaturated soil. In this paper, the water content to determine the unsaturated soil shear strength calculation formula of the parameters in order to determine the strength of unsaturated soil, the practical project has a guiding significance.
