Study Cast-in-place Curved Box Bridge Damage Analysis And Repair Reinforcement Engineering Application

In recent years, curved bridge disease appeared in large numbers, along with a widerange of applications situ box girder bridge curve. The reason was the designer lack ofknowledge about temperature, eccentric of some curved girder bridge and possibleoverload.Therefore, it was a very meaningful work to research concrete box girder curvebridge repair and reinforcement technology.Firstly, using the high praise of the West Approach Bridge and at the intersection of thevertical line five, including A, B, C, D, E, F, G, H ramp as relying engineering. It investigatedthe bridge disease situation, analyzed the causes, and produced a clear mechanism ofdisease.Secondly, according to disease in relying engineering, it designed calculations forreinforcement analysis to adjust torque distribution as the primary purpose of bridgereinforcement, and used Midas Civil to establish a finite element model of carrying capacity,rigidity and stability around the reinforcing structure. After calculating contrast analysis,it gota rational reinforcement design.Finally, it gave the program and key construction process in strengthening the design andconstruction projects.In short, through the analysis of disease concrete box girder bridge and curve repair andreinforcement technology, it proposed reinforced technology and reinforcement methods tofit the curved box girder bridge, provided technical support and reinforcement theory, designand construction of the new cast curved box girder bridge foundation.
