摘要

提出了一种新的岩土材料微细结构光学图像测量方法。实现了常规土工三轴实验与岩土材料微细结构的联合测试，获得了土体在荷载作用过程中微细结构变化清晰的图像序列，不仅可以定量研究土体在荷载作用下微结构的变化情况，还可利用数字图像相关技术对微细结构图像序列进行相关分析，得出土颗粒在荷载作用下的微观位移场，为建立土体合理的本构关系模型提供试验依据。

Abstract

A new optical image measurement method of soil and rock microstructure is presented. the soil sample can be measured by general triaxial experiment and optical image measurement at the same time. This method can obtain clear image array of soil microstructure of the same soil sample under different loads; it can be used both in quantitative analysis of soil microstructure change and in measurement of soil micro-displacement field under different loads.
