| 摘 要： | 为了分析高含水率疏浚淤泥流动固化土的强度特性,对疏浚淤泥流动固化土进行了三轴剪切试验研究.通过三轴试验仪,开展了不同配比和不同龄期的流动固化土的固结不排水(CU)三轴剪切试验.结果表明,疏浚淤泥流动固化土的抗剪强度包线由双折线组成,屈服前的强度包线与水平轴近似平行(平均夹角为4.8°),屈服后的强度包线与水平轴夹角增加...

| Abstract: | In order to investigate the strength properties of the flow-solidified soil of dredged clays with high water content,triaxial shear tests were carried out.The consolidation-undrained triaxial shear test for the flow-solidified soil with both different mixing proportion and different curing time were performed by triaxial apparatus.The experimental results show that the shear strength envelope is formed by double broken line for the solidified soil through triaxial shear test.The strength envelope is nearly ... |
