| 摘 要： | 本文首先介绍厦门某地两种具有代表性的原状残积土(花岗岩残积土)室内三轴不排水动力剪切实验所得到的残积土在循环荷载作用下表现出来的诸如周期抗剪强度,动弹性模量以及等效阻尼比等动力学性质及其有关的重要参数;继而分析了花岗岩残积土在周期剪切过程中强度、变形、应力路径及孔隙压力等方面所具有的特点,以图揭示它们的内在规律;最后讨论了残积土周期荷载作用下归一化性状及动强度的确定方法。

| Abstract: | In order to determine behavior of Xiamen residual soil under cyclic loading, triaxial test with undrained conditions has been conducted in this paper. First, some important dynamic parameters such as strength, elastic modulus and damping ratio have been determined. Secondly, behavior of stress-strain, stress path and excess pore water pressure under cyclic loading has been analyzed. Finally, both the normalization and the determination of dynamic strength index ?d and ?d for residual soil have been discussed. |
