摘要
在膨胀土物性试验的基础上,进行了不同初始含水量条件下的膨胀土三轴压缩试验,得出了三种含水量膨胀土饱和试样的应力应变曲线;通过三组试验曲线的对比,发现三者之间存在明显的差异,直观地反映出初始含水量对膨胀土本构关系的重要影响,并找出了较优的含水量,为解决膨胀土实际工程问题提供了参考依据。
On the basis of physical property tests for expansive soils, the triaxial compressive tests are conducted on expansive soils with various moisture contents, which gives the stress-strain curves for saturated specimens having three different moisture contents; it is found through comparison between those curves that they have obvious difference, directly reffleeting the major effect of the initial moisture contents of exparsive soil's constitutive relationship and the results give a better moisture content, which suppply referential basis for solving practical engineering problems coneerming expansive soils.
