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。
做瞭12箇同時控製吸力和淨圍壓的非飽和含黏砂土三軸剪切試驗，旨在探討吸力、圍壓對非飽和含黏砂土濕化變形的影響，建立瞭計算濕化變形的兩種模型，併將試驗結果分彆代人兩種模型得齣：在相同圍壓作用下，吸力越大試樣的濕化變形量越大；相同吸力作用下，圍壓越大試樣的濕化變形量越小。
주료12개동시공제흡력화정위압적비포화함점사토삼축전절시험，지재탐토흡력、위압대비포화함점사토습화변형적영향，건립료계산습화변형적량충모형，병장시험결과분별대인량충모형득출：재상동위압작용하，흡력월대시양적습화변형량월대；상동흡력작용하，위압월대시양적습화변형량월소。
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.
