| 摘 要： | 做了12个同时控制吸力和净围压的非饱和含黏砂土三轴剪切试验，旨在探讨吸力、围压对非饱和含黏砂土湿化变形的影响，建立了计算湿化变形的两种模型，并将试验结果分别代人两种模型得出：在相同围压作用下，吸力越大试样的湿化变形量越大；相同吸力作用下，围压越大试样的湿化变形量越小。

| Abstract: | In order to discuss suction,net cell pressure to affect unsaturated clayey sand wetting deformation, 12 triaxial drained shear test with controlled suction and net mean cell pressure were conducted. ：2 models of computing wetting deformation were founded. At same time, substituting test results to 2 models could obtain that the more suction, the sample wetting deformation were bigger under the same net cell pressure. The bigger net cell pressure, the sample wetting deformation were smaller under the same suction. |

| Keywords: | unsaturated soils subgrade wetting deformation suction |
