摘要: 从非饱和土理论出发,对非饱和土的水-气转换、非饱和土的强度以及堤防稳定分析方法进行了初步探讨,重点探讨了非饱和土抗剪公式的简化问题,并在边坡稳定分析中引入了吸力对抗剪强度的影响,使常规的稳定分析程序更为合理。

Abstract: On the basis of the theory of unsaturated soils, thpaper discusses the air-water transform of unsaturated soils, its strength, and stability analysis in the dike of the Yangtze River. The short-cut formala of shear strength of unsaturated soil is emphatically presented, the compact of suction force on the shear strength is considered in stability analysis, and the concerned programs are more resonalde.
