Analysis of Cracking Reasons and Real-time Identification of Structural Status of Prestressed Continuous Box Girder Deck Slabs
Taking a prestressed continuous box girder bridge as the engineering background,this paper analyzes the causes of cracking in the bottom plate and web plate of the main beam of the bridge during operation,and proposes disposal suggestions.This article first introduces the damage situation of the main bridge and the structural response under static load tests.Then,the longitudinal stress of the structure is an-alyzed using finite element simulation method,and the influence of structural parameters and usage loads on the transverse cracks of the structure is obtained.Finally,an analysis and summary of the causes of box girder crack diseases were conducted,and crack prevention and control measures were proposed.
