| Abstract: | In this study,the characteristics of a geotechnical CT visualization system are introduced and the application of CT technology for soil testing are systematically summarized,including research advances in the observation of the initial structures of soil and the structural evolution of loess,frozen soil,expansive soil,and coarse-grained soil.In addition,this study indicates potential future research directions,including the development of quantitative computer imaging analysis systems,the use of the mesoscopic structures that are visualized by CT images for the establishment of numerical models,and the development of CT scanning devices for dynamic soil testing. |
