【摘要】 软粘土抗剪强度指标试验方法在工程中应用广泛.直剪和三轴试验模拟饱和软粘土地基实际受力状态,存在安全系数小、规范不足等问题.基于此,提出对于饱和软粘土地基上快速填筑防洪堤时,宜在遵守规范的前提下,尽可能采用十字板试验成果复核堤防边坡稳定,并反演快剪强度指标对比,使工程设计更趋合理.更多还原

【Abstract】 The test methodology and application in engineering for parameters of shear strength of soft clay are presented.The deficiency of simulating actual stress state of soft clay by direct shear test and triaxial test and its effect on engineering design are analyzed.For fast filling levee on the foundation of saturated soft clay,it is proposed that the results of vane shear test should be adopted for evaluating the stability of embankment slope on the premise of compliance with specifications,and should be compared with inversed parameters of shear strength from quick shear test,which would contribute to more reasonable engineering design.更多还原
