Abstract

In order to study the impact of train load on deformation of big-diameter shield tunnel, the Vehicle-Track-Tunnel-Soil coupling dynamic model was established, and the reaction force of fasteners was used to transmit between the Vehicle-Track coupling dynamic model and the Tunnel-Soil finite element model. The results are as follows: the changing of vertical cross section deformation and horizontal cross section deformation has congruent relationship with the changing of train load and there exists a time difference; under the impact of train load, tunnel size increases in vertical direction and shrinks in horizontal direction, cross section shape grows into vertical oval and the deformation is confined to a very small amount.
