| 摘 要： | 为了分析南水北调中线工程安阳段渠坡的稳定性,对该渠坡换填土在不同含水率下进行了不固结不排水三轴剪切试验.研究结果表明:剪切速率对基质吸力的影响较大,而对强度的影响较小；通过比较确定了合适的剪切速率；含水率相同的试样在不同围压下的强度值在pf -qf坐标上呈良好的线性关系；得到了试样在不同含水率下的总强度指标,建立了总内...

| Abstract: | In order to analyze the stability of the bank slope at Anyang district for South-to-North water diversion project,a series of unconsolidated-untrained triaxial shear tests under different moisture content are carried out on the remolded cohesive soil of the slope.The test results show that the shear rate holds greater effect on matric suction than that on strength.The proper shear rate for the specimens is determined by comparison;for the specimens of the same moisture content,their strength show a strong l... |
