摘要

自行研制了准平面应变试验装置，利用该装置在不同加载速度和不同含水率条件下对重庆红色泥砂岩的变形局部化进行了试验研究，并利用弹性波方法测定了变形局部化的起动时间。结果表明，在平面应变条件下，泥砂岩的局部化带倾角与加载速率之间存在类对数关系，研究结果也证明了局部化起动时间受加载速度与含水率的影响较大。

Abstract

A quasi-plane strain experimental device is designed. This device is implemented to analyze deformation localization phenomenon of Chongqing red mud-sand stone in quasi-plane state. Some specimens are tested in various loading speeds; and some are researched with different water contents. During the experiment

the onset of deformation localization has been monitored by elastic wave. The results show that

in quasi-plane strain state

there is a logarithm-like relation between the angle of localization band and loading speed. It is also shown that the water content could impact on the onset of deformation localization.
