摘要
笔者以杨陵黄土为对象,进行了原状黄土和击实黄土单轴抗拉的三轴抗拉试验。详细探讨了黄土抗拉强度和含水量、干密度、饱和度及基质吸力的关系,同时提出了黄土抗拉强度与基质吸力的关系表达式。用实验资料验证了几种典型断裂破坏准则对黄土的适应性,并根据黄土的破坏特性,建立了相应的断裂破坏准则。
In this paper, intact loess samples and disturbed loess samples of Yangling are studied by using uniaxial and triaxial tensile tests. Based on the results of tests, the relations between the tensile strength and water content, density, saturation degree as well as the matrix suction are approached respectively, and expression of the relation between the tensile strength and the matrix suction are presented. Adaptabilities of several typical rupture failure criterion for loess are validated by experiment data. Moreover, depending on the failure characteristics of loess, the rupture failure criterion of loess is established.
