| 摘 要： | 用一系列吸力增量与净平均应力增量之比为常数的三轴排水固结试验探讨了非饱和土在p-s平面上的屈服特性、变形特性和水量变化特征，曲试验结果得到了初始屈服服线的形状、压缩指数和变化规律和广义土－水特征曲线，改进了Alonso提出的非饱和土的弹塑性模型。

| Abstract: | A series of triaxial consolidation tests were conducted to study the yield locus on p -s plane and deformation as well as water content change of an unsaturated soil. The initial yield curve, the law of compression index change and a generalized soil-water charac- teristic curve of the unsaturated soil are obtained from the test results. The elasto-plasticity model of unsaturated soil proposed by Alonso et al is modified in this paper. |

| Keywords: | unsaturated soil loading path yield general soil-water characteristic curve |
