Patent number: 12385856Abstract: The subject invention pertains to a suction-controllable triaxial test system and a method for studying the micro-hydro-mechanical behavior of unsaturated soils through the visualization of the in-situ evolution of three-dimensional (3D) microstructure upon triaxial loading in a ((p-ua), q, s) space. The triaxial apparatus can be small enough to be operated within a micro-focus or nano-focus X-ray CT scanner. Internal characteristics and 3D movements of soil particles and the water and air in soil pores can be visualized during in-situ controllable hydro-mechanical loading processes without disturbing the soil sample. The evolution of 3D micro-structure of unsaturated soil samples of varying matric suction can be directly related with their element-scale behavior for conducting cross-scale fundamental studies.Type: GrantFiled: May 3, 2022Date of Patent: August 12, 2025Assignee: The Hong Kong University of Science and TechnologyInventors: Kwan Anthony Leung, Jianbin Liu
