摘要

红粘土工程性质特殊而复杂引起学术界与工程界的广泛关注。采用CT技术研究三轴应力条件下红粘土的力学特性，是土力学领域中一项新的研究方法，它可以从细观的角度分析红粘土在受到三向应力作用后，土体内部结构、孔隙的变化、裂隙扩展等规律，并获得CT图像、CT数与应力-应变的关系。

Abstract

The mechanical properties of red clay under triaxial stress are studied by using CT technology

which is a new kind of research method in soil mechanics. During the red clay is under triaxial stress

the regularities of clay’s inner structure

pore change

fissure extending and so forth are analyzed from meso-angle; and obtained the CT images and the relatives of the CT numbers and stress- strain are obtained by the new technology.
