摘　　要：通过对膨胀土湿化变形的反复试验 ,分析了不同应力水平下的湿化变形试验全过程中应力 -应变曲线和体变 -轴向应变曲线以及湿化后的抗剪强度 ,其成果对工程实际具有重要的参考价值 .Through a lot of tests for slaking deformation of expansive soils, behaviors of stress_strain and volumetric strain_axial strain in the complete process are studied at different values of stress level in the soaking tests. The shear strengths of expansive soils after slaking are obtained as well. The results obtained may be applied in geotechnical engineering practice.
