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.
