| 摘 要： | 针对非饱和黄土具有的特殊结构强度,进行了不同剪切速率下的直接剪切试验和三轴试验,通过分析不同剪切速率和不同垂直压力对直剪抗剪强度的影响,得出了与饱和软土不同的结论,并指出非饱和黄土直接剪切试验的剪切速率宜为1.0 mm/min。

| Abstract: | Under different shear rates of direct shear tests and triaxial tests were done for special structural strength of unsaturated loess. A con-clusion is obtained which different from the saturated soft soil shear strength by analyzing the different shear rate and different vertical pressure effects on direct shear shear strength,points out the shearing rate in unsaturated loess soil direct shearing experiment is favorably 1. 0 mm/min. |
