| 摘 要： | 在土力学中，非饱和土的抗剪强度一直是研究人员所关注的重点。土体的抗剪强度随含水量的不同变化明显。试验以云南某重塑土为研究对象，采用常规直接剪切试验为手段，对不同含水量土样的抗剪强度参数进行测定。试验结果表明，土样的抗剪强度不是单调地随含水量的增加而降低，而是呈现出有起有伏的抛物线状，对进一步认识土体强度随含水量变化规律有积极意义。

| Abstract: | The research on shear strength of unsaturated soil is important in soil mechanics research. The shear strength of soil depends on the difference of water content. Based on the object of remolded soil in Yunnan province and the means of the direct-shear tests, the author surveyed the shear strength parameter of soil with different water content. According to the test results, the shear strength of soil don＇t decreased monotonously with the increasing of water content, interest of a parabola with up and down,which is some positive significance to know the relationship of between soil strength and water content. |
