Abstract
Based on a practical case of a prestressed continuous rigid frame bridge disease investigation,the paper analyzes and finds that there are inclined cracks in the web,longitudinal cracks in the bottom plate and cracks in the roof of the bridge.The cracks are densely distributed and some cracks are deep,which have a serious negative impact on the quality of the project and the potential driving risk is greater.Midas/Civil finite element software is used to build an analysis model,explore the specific conditions of bridge load and prestress loss,and propose targeted reinforcement schemes.After the reinforcement treatment,the prestress index of the bridge returns to the standard level,the stress state is effectively improved,and the ideal reinforcement effect is obtained.关键词
