| Abstract: | The author makes 3D FE analysis on the influence of the foundation pit excavation on the horizontal displacement of the pile foundation of the surrounding bridge by Drucker Prager model and interface element. The author also analyzes various factors that influence the horizontal displacement of the bridge pile foundation during the foundation pit excavation. This paper provides basis for the determination of the design scheme. |
