Abstract

The design of shield lining segments is mostly calculated by load-structure method. The rationality of structural calculation mainly depends on the structural model and the accuracy of the applied loads. At present, the models used in shield tunnel segment design mainly include: beam-spring model and beam-joint model. The beam-joint model is more accurate, but the simulation is mostly realized by self-programming. In this paper, the numerical simulation is carried out by the general finite element software ANSYS. The two types of models are compared and analyzed, and the action load is analyzed by the beam-joint deformation discontinuity model.
