膨胀土湿化变形特性的试验研究

Test study on wet deformation of expansive soil

膨胀土湿化变形的一维试验问题早已解决 ,而在实际复杂应力状态下 ,土的膨胀必然是多维 ,而且各向的膨胀量也不同。文章通过应用控制式对称三轴压缩仪进行膨胀土的三维湿化变形测试 ,研究运用膨胀土筑坝时土体的湿化变形特性 。

The question about one dimension test of wet deformation of expansive soil was solved. The expansion of soil is multi dimension certainly and the swelling capacity of different direction is different in practical complex stress state. In order to research the peculiarity of wet deformation of expansive soil, three dimension wet deformation of expansive soil with controllable symmetrical triaxial compression apparatus and corresponding countmeasures are put forward.
