摘　　要：简要论述了CT技术的基本原理。通过与SEM及AE方法的比较,肯定了CT技术在岩土工程研究中的适用性。概述了CT技术在岩土体受力过程中的裂隙发育、土体结构性的变化、土壤中的大孔隙研究、岩土体动三轴及冻土CT检测等方面的应用现状。The basic principles of CT are briefly discussed. Compared with SEM and AE methods, the applicability of CT on Geotechnical Engineering study is confirmed. Today, the application of CT in Geotechnical Engineering lies in： the evolution process of rock crack under loading, the change of soilmass structure, study of the macro- pores of soilmass, the change of silty clay before and after dynamic triaxial test and Real - time CT test in frozen soil.

关 键 词：CT技术 岩土工程 裂隙发育 结构性
