| 摘 要： | 本文从非饮和土中微观孔隙中分离规律出发，考虑到土孔隙内收缩膜对非饱和土剪切强度的影响，推导出了非饱和土土水特征曲线方程和结构强度公式。这不仅揭示了两者的内在联系，而且使它们有了统一的理论基础。这些公式既与试验测量结果相符，又便于实际应用。

| Abstract: | Based on the structural model of unsaturated soil and with the influences of the meniscus in pores of soil considered,the equation of soil-water characteristic curve and the formula of shear strength were derived.This not only revealed the inner relationship between the soil-water characteristic curve and shear strength of the unsaturated soil,but also gave the unified theoretical foundation for both of them.The theoretical results are well consistent with data of tests and beneficial to practical applications. |
