Numerical Simulation and Calculation Analysis of Suspension Bridge Anchorage System

Abstract:

Based on the background of Xinghai Bay Sea-crossing Suspension Bridge, it reviews the development process of Suspension Bridge anchorage and describes the static theory of gravity anchorage of suspension bridge. Using the soft ansys, a three-dimension finite element model of the suspension bridge anchorage is established to analyze the overall stability of the anchorage foundation, the displacement and stress conditions. The anchorage in various load conditions of displacement and stress is studied by numerical calculation and comparison. The analysis result shows that the first slip area is not in the outer end of the contact surface, and there is a certain distance. The area beginning to slip also increases with the loading nodes increasing. As the level of the load increases, the slip region has gradually developed, the contact surface in the first sliding part opens slowly. The slip area expands to the entire contact surface except for a contact surface opening area with the contact surface in sliding failure.
