摘要

借助于红砂岩冻融循环CT扫描试验

从扫描层面内不同的感兴趣区域内CT均值数大小及其变化以及CT图像

对4种典型的不同初始饱水状态红砂岩进行冻融循环条件下损伤扩展差异性研究。研究结果表明

对于初始损伤相同的岩石

初始饱水状态将决定冻融循环对其损伤扩展的影响程度。

Abstract

Results obtained from CT scanning test of red sandstone under the condition of frost and thaw

different damage extension of four different classical initial water-saturated red sandstones was studied under the condition of frost and thaw. All results especially depended on CT-means and CT-figures in different interested zone in CT scanning plane. The research shows that the degree of damaged extension is determined by initial water-saturated state for the same initial damaged rocks.
