Study on the settlement caused by the Maglev train

Because of the high speed, the operation safety of Maglev train is heavily affected by the differential settlement. As the first commercial service, the operation of Maglev train has been for a few years in Shanghai, which provides us a chance to investigate the settlement along the magnetic suspension line and the subsidence induced by Maglev train. In this paper, the influence of the operation of the Maglev train on the subsidence of different soil layers has been studied using the data obtained from the layerwise marks. The study results indicate that the differential settlement along the magnetic suspension line occurred, different soil layers presented different deformation features, and the operation of Maglev train has increased land subsidence.
