软黏土地基土体抗剪强度若干问题OA北大核心CSCDCSTPCD
Some problems concerning shear strength of soil in soft clay ground
针对不少土力学教材和规范规程认为由UU试验得到的是饱和黏性土的抗剪强度指标,将黏性土不排水抗剪强度视为土的抗剪强度指标的错误概念,首先分析了土的抗剪强度和抗剪强度指标之间的区别,然后通过分析三轴固结不排水剪切试验和土的抗剪强度指标的测定,三轴不固结不排水剪切试验和土的不排水抗剪强度的测定,讨论了黏性土不排水抗剪强度和抗剪强度指标之间的区别。通过软黏土地基中土体的抗剪强度及测定方法的讨论,再次说明了黏性土不排水抗剪强度和抗剪强度指标之间的区别。最后…查看全部>>
Some concepts of shear strength and shear strength parameter,undrained shear strength and unconsolidated-undrained triaxial test are wrong in some soil mechanics textbooks and geotechnical engineering codes.The differences between the shear strength and the shear strength parameter are firstly discussed.Then the shear strength parameters determined by means of the consolidated undrained triaxial tests and the undrained shear strength determined by unconsolid…查看全部>>
