Abstract: Centrifugal model tests and numerical simulation are conducted to investigate behaviors of ground settlement due to groundwater exploitation and to demonstrate the influence of land subsidence on three types of bridges.By use of the elasto-plastic finite element analysis method,the structural transformation of the bridge in the typical section of the high speed railway with the influence of land subsidence is studied.At the center district of land subsidence and in the vicinity of the well,the asymmetrical subsidence is more serious,and has larger influence on the bridge structure than the regional land subsidence does.It can be prevented and cured by adopting engineering measures.
