Abstract:In order to study the bearing capacity and safety of the frozen wall,taking the entrance and exit of a subway in Tianjin as an example,a three-dimensional numerical model under the pressure of the surrounding rock was established based on the load structure method and calculated,and the in-ternal force and deformation of the frozen wall under the load of the surrounding rock were analyzed.The results showed that under the action of the pressure of the surrounding rock,the stress concen-tration of the upper span of the frozen wall was concentrated,the maximum stress was 0.518 MPa,and the maximum displacement deformation was 7.284 mm.
