In this paper, triaxial compression experiments on remolded soil were carried on by simulated the stress path of vacuum preloading method. With Industrial Computer Tomography(ICT), the pore micro-structure in soil samples on different load phases were studied. The number of pores was decreasing in trend, and pore area gradually became smaller. Shape factors gradually became larger, and the pore shapes were rounded. Direction angle tends to unity, orientation become better. In addition, the relationships between compression and pore surface area ratio, strength with deformation , pore size with shape factor, permeable nature and pore orientation in vacuum preloading process were established.
