Research on Transverse Prestressed Carbon Fiber Sheet Reinforcement Technology for Existing Hollow Slab Beam Bridge
Hinge joint damage will weaken the overall performance of prefabricated hollow slab and affect the bearing capacity of the structure.Therefore,it is particularly necessary to reinforce the hollow slab bridge with hinge joint disease.This paper first analyzes the common hinge joint diseases of prefabricated hollow slab bridge,then studies the reinforcement scheme and construction technology according to the causes of the diseases,and finally evaluates the reinforcement effect through load test.The results show that the transverse distribution coefficient of 8#beam is improved by 8.9%under eccentric load condition;under the normal load condition,the transverse distribution coefficient of 5#beam is improved by 9.3%.
