Research on Health Monitoring and Evaluation Method for Prestressed Concrete Cable-stayed Bridge
In modern transportation construction,prestressed concrete cable-stayed bridge is widely used in urban roads and expressways because of its advantages of large span,high stiffness and strong durability.However,with the increase of bridge's service time,the structure will be affected by various external environmental and internal mechanical factors,resulting in a decline in health conditions and even potential safety hazards.In order to detect and solve health problems of prestressed concrete cable-stayed bridges in time,this paper combines the actual engineering case and uses the finite element simulation method to conduct health monitoring of the bridge.The results show that analyzing the displacement and stress distribution of the bridge through numerical models can effectively judge the health conditions of the bridge.
