As a type of non-circular section corridor in the construction of underground comprehensive pipe corridors, the uplift process of rectangular pipe corridors has a more complex impact on the surrounding soil compared to traditional circular corridors. However, there is currently limited research on the pipe-soil interaction during the uplift process of rectangular pipe corridors. To address this issue, a transparent soil model test was conducted to study the pipe-soil interaction during the uplift process of rectangular pipe corridors. The focus was on measuring and analyzing the changes in the p-y curves of the rectangular pipe corridors at different densities and burial depths, as well as the displacement field changes of the surrounding soil. The research findings indicate that the p-y curve trends at different burial depths of the rectangular pipe corridor exhibit similar characteristics under varying densities, going through phases of linear increase, peak variation, rapid decline, and gradual decrease. The greater the density and burial depth of the rectangular pipe corridor, the larger the amplitude of change and the maximum bearing capacity. The displacement field changes of the soil at the same burial depth during different stages of the uplift process are similar, with the surrounding soil displacement transitioning from an overall upward movement to localized upward movement at the upper and lower sections of the corridor while the surrounding areas move downward. Additionally, at the same density and burial depth, the angle of the displacement change surface of the soil increases with the height of uplift.
