摘要
首先回顾了非饱和土剪切强度的研究现状，接着在控制吸力非饱和土三轴剪切试验的基础上提出了非饱和土剪切强度的双曲模型，它可预测不同吸力对强度的贡献———τｓ ，预测结果令人满意，具有很好的实用性。
The current state of research on the shear strength of unsaturated soils is reviewed in this paper. And the hyperbola model of shear strength theory is presented based on the triaxial shear test results of the unsaturated soils. It can be used to predict the suctional strength. The predicted results are very good, which show that the hyperbola model is of practical value for geotechnical engineering.
