摘要：
In China, with the development of the high speed railway, subgrade settlements control has been a key factor of railway operation and safety. Based on the study of field test data of settlement plate surface subsidence and magnetic ring subsidence in deep layer, using ABAQUS FE simulation method, the settlements of composite foundation of wide yard station were calculated, the finite element settlement control model was established, and the regularity of composite foundation settlements and its relation with stress variation were analysed in this paper. The simulation results of settlement regularity matches well with observation results of field test data, verified the reliability of the model.
