-
摘要: 阐述了应变路径试验研究的意义、试验技术和试验步骤,对如何改善应变路径的控制精度提出了具体方法。作为应用,文中介绍了用应变路径试验方法研究砂土应变软化的一些成果。试验结果表明,应变路径对砂土的硬化和软化有很大影响Abstract: The significance of using strain path testing in the study of soil behaviour is highlighted in this paper. The testing techniques, testing procedures, and the control accuracy are discussed. Strain path testing results on dense sand are presented which show that the strain hardening or softening behaviour of dense sand is greatly influenced by the strain path controlled during the testing.
