简要介绍了长江科学院岩土试验CT工作站以及与之配套的CT三轴仪、渗透仪研制情况。阐述了近年来利用CT技术在粗粒土组构、砾石土浸润试验、膨胀土干湿循环试验、水力劈裂试验、加筋土试验研究等方面研究的初步成果，展示了不同岩土试验CT图像的效果，显示了CT技术在岩土试验中的作用，以期引起岩土工作者的关注，推动岩土试验的发展。

This paper briefly describes the geotechnical testing CT workstations of Yangtze River Scientific Research Institute, as well as the development of ancillary CT triaxial apparatus and infiltration instrument. By introducing the preliminary results of applying CT technology in fabric study of coarse-grained soil, infiltration tests of gravel soil, wetting-drying cycles study of expansive soil, and hydraulic fracture study, as well as and reinforced soil, this paper displays CT image effects of different geotechnical tests, and demonstrates the role of CT technique in geotechnical tests in the hope of arousing the concern of geotechnical practitioners，and hence promotes the development of geotechnical testing.
