This study analyzes differences in macro-deformation between saturated intact loess and saturated remolded loess under the same stress state from the perspective of micro-pore distribution. Moreover, the study analyzes differences in the micro-pore size distribution between saturated intact loess and saturated remolded loess in a similar void ratio. Mercury intrusion tests are conducted on saturated intact and remolded loess in Cuishi village, Jingyang county, after one-dimensional and isotropic compression under the state of same stress and a similar void ratio. Results show that (1) The pore distribution of Jingyang intact loess has three peaks while that of remolded loess has two peaks. Moreover, there are differences in the highest peak changes in the remolded loess as compared with that of the intact loess. (2) Under the same stress state, the volume of intra-particle pores is similar in both loess samples but that of the interparticle pores is different. With an increase in stress, the volume of interparticle pores of both specimens becomes more similar, and differences in the macro-deformation are reflected in the differences between the interparticle pores. (3) Under a similar void ratio state, the pore distribution of the two loess samples are similar, but their stress paths are considerably different.
