| Abstract: | Heigou Bridge is a prestressed concrete continuous rigid-frame bridge with High-piers,which main span is 150m.This bridge is in the face of the gorge,where wind speed is large.In this paper,the construction process of bridge has been simulated by establishing a model with finite element method;and the structural dynamic behavior and the stresses and deformation under wind load have also been studied,which will provide reference for bridge construction and control. |
