| Abstract: | Based on the construction of the underground passage beneath Changchun railway station,the surface subsidence caused by tunneling beneath railway was studied. The finite plane element model was established to simulated the procedure of tunneling. The rules of surface subsidence and the maximum subsidence were obtained by loading with conventional even quasi-static train loads. It guarantee the construction goes on smoothly and safely. |
