Foundation Soil Stability of Immersed Tunnel Subjected to High Speed Train

Sun Xiaojing, Liu Weining
The effect on the base of a railway immersed tunnel by the high speed train was studied in this paper. The liquefaction of the tunnel sand foundation under the water was estimated by using the method of numerical simulation. It is found that there will be very large capacity in the sand foundation to endure the periodical load of high speed train.
