摘要: 本文介绍了我国某海区海洋土应力-应变与强度特性,列举了各种试验(三轴剪切试验、单剪流变试验和压缩试验)的典型结果。试验表明:三轴试验显示其本构关系符合邓肯-张双曲线理论,在超压密状态和一定深度下的海洋土均会产生负孔隙水压力,并找出孔压系数 B 与 A_f 的关系;压缩试验与单剪流变试验的应力-应变关系符合幂函数关系;另外,对应力途径、弹性模量等也作了初步分析,为今后深入探索海洋土的性质积累资料。
Abstract: The stress-strain and strength properties of marine soils in a sea area in China, with typical results of triaxial shear test, simple shear rheological test, and consolidation test are presented in this paper. Trianxial test shows that the constitutive relationship of this kind of soil is consistent with Duncal-Chang’s theory, the relation between pore pressure parameters B and Af is found. The stress-strain relationship keeping with power function is obtained from consolidation test and the simple shear rheological test. In addition, preliminary analyses of the path dependent property and the modulus of elasticity of this kind of soil are carried out, which provides valuable material for further research on marine soils.
