Short-Term Deformation Monitoring Analysis for a Large Span Cable Stayed Bridge

Based on a large span cable-stayed bridge in Chongqing, this paper analyzes the bridge alignment, vertical displacement and deviation of cable tower, expansion joint deformation and cable force during operation. The study calculates related theoretical values of bridge deformation by using finite element software. The security situation of the bridge is then evaluated on the foundation of contrastive analysis of the calculated values and measured values, which provides some basis for similar bridge monitoring.
