| 摘 要： | 用净平均应力和吸力等于常数、偏应力增大的三轴排水剪切试验，探讨了剪切对非饱和土水量变化的影响。试验结果表明，土-水特征曲线依赖于偏应力，改进了非饱和土中水量变化的本构关系，建立了含水量．吸力．净平均应力．偏应力形式的土．水特征曲线。

| Abstract: | A series of triaxial drained shear tests with controlled net mean stress and suction equaling constants were conducted to study the effect of shear on soil-water characteristic curve of unsaturated soil. The test results show that the soil-water characteristic curve is dependent on deviatoric stress. The constitutive equation of water content change of unsaturated soil is modified. The soil-water characteristic curve including water content, suction, net mean stress and deviatoric stress is proposed. |

| Keywords: | unsaturated soil shear deviatoric stress soil-water characteristic curve |
