Mechanical Behavior of a Piled-Raft Foundation for a High-Speed Railway Subjected to Train Loading
In this paper, numerical simulation with soil-water coupling finite element-finite difference (FE-FD) analysis is conducted to investigate the settlement and the excess pore water pressure (EPWP) of a piled-raft foundation for high-speed train (speed: 300km/h) due to cyclic train loading. To demonstrate the performance of this numerical simulation, the changes of the settlement and EPWP of Shanghai soils under train loading within one month was calculated and confirmed by monitoring data, which shows that the change of the settlement and EPWP can be simulated well on the whole. Based on the results obtained in this paper, it is possible for us to predict the long-term settlement and the changes of EPWP far longer time than one month using the proposed numerical method.
