【 摘 要 】

The internal force and deformation of the adjacent bridge pile foundation is influenced by newly Seawall with inner epeirogenic through blowpipe, which may endanger the normal operation of the bridge. Using Plaxis3D software in this paper, the subsoil is used by the Hardening Soil model, and analysis the mechanism of the influence of bridge pile foundation by the newly Seawall with the inner epeirogenic through blowpipe when the distance between Seawall and bridge is changed from 200m to 250m, 300m, 350m and so on, which provides reasonable safety distance between the Seawall and bridge. The analysis results show that the vertical displacement and internal force of bridge pile foundation is less affected by the newly Seawall with the inner epeirogenic through blowpipe, which will not affect the bearing capacity of the bridge pile foundation. However, the horizontal displacement of pile foundation of the bridge is greater influenced by newly Seawall with the inner epeirogenic through blowpipe, which will affect the normal operation of the bridge. As long as reasonable rate is controlled by epeirogenic through blowpipe, the max horizontal displacement of pile foundation can meet the design requirements when the distance is 300m between Seawall and bridge.
