摘要
本文以有效应力原理为手段,对固结不排水剪(CU 试验)、不排水剪(UU试验)和排水剪(D 试验)三种常规三轴剪切试验成果进行了分析,将试验成果用有效应力路径统一起来,相互印证。结果表明,三种三轴剪切试验方法得到的抗剪强度是抗剪强度随时间变化曲线上三个特定点。进一步证明了抗剪强度与有效应力的唯一对应关系,即有效应力路径决定着土体的强度和变形的产生和发展。
This paper has carried an analysis on the results of three traditional triaxial shear tests by means of the effective stress principle,and put them together by using the effectise stress route and made them testify each other. The result shows that the strength of shearing obtainted through the three shear test is the three identical points on the curves of shear strength-time.It testifies further the only corres-ponding relationship of shear strength with effective stress,that is the effective stress route decides the formation and the developing process of the strength and deformation of soil body.
