| 摘 要： | 非饱和土不同于饱和土的根本原因就是非饱和土中吸力的存在。对于一般土体来说,非饱和土体的吸力主要是指它的基质吸力。非饱和土的基质吸力随着含水量的变化而变化。根据黄河大堤非饱和土工程特性的试验结果,用极限平衡法分析黄河大堤边坡稳定性,得出基质吸力对边坡影响的规律。

| Abstract: | The fundamental difference between unsaturated soil and saturated soil is that there is suction in unsaturated soil.For general soil mass,unsaturated soil suction mainly refers to its matric suction.Matric suction of unsaturated soil changes when water content changes.In this paper,based on the test result of engineering characteristics of unsaturated soil of Yellow River Embankments,the stability of slope of Yellow River Embankments is analyzed using ultimate equilibrium method and the influencing rule of ... |
