| 摘 要： | 探讨非饱和土的饱和度测量几种测量方法。由于非饱和土试验方法的不同,造成饱和度的测量的偏差。本文根据GDS的试验结果,对几种测量饱和度的方法进行比较和分析,指出假设土样颗粒体积不变,土样体积改变是因为土样孔隙大小的改变的合理性,认为直接法是一种有效的方法。

| Abstract: | The paper explores several methods measuring degree of saturation in unsaturated soils.Different test methods for the degree of saturation in unsaturated soils can result in different results.According to the tests by GDS triaxial cell,the paper compares and analyzes these methods.It is pointed out that pre-assumption of soil grain volume being invariable is logical. Therefore,the change of specimen volume is equal to the change of soil specimen pore.The direct method is an effective method for measuring degree of saturation. |
