| 摘 要： | 采用大型三轴仪,对双江口坝壳粗粒料进行了不同围压、不同应力水平的湿化试验研究,并对湿化变形后的抗剪强度进行了分析.各个湿化应力水平下的抗剪强度指标近似相等,其c值在风干态和饱和态之间,更接近于饱和态值,而( 值也有相同规律,其值较固结排气剪略有降低,更接近于饱和态的摩擦角.

| Abstract: | Using the large triaxial apparatus, the wetting character of coayse-grained material for Shuangjiangkou dam is studied under different confining pressures and different wet stress levels; and its the shearing strength after wet distortion. Is analyzed The shearing strength indices approximately equal under different wet stress levels; its c value is between in air-dried condition, and saturated condition, approaches the valu in saturated condition; but the ? has the same rule, its value slightly below the consolidated air exhaust shear test, value and approaches in value in saturated condition. |
