Application and Theoretical Analysis of Hollow Slab Bridge Reinforcement Technology
This paper briefly describes the common diseases of hollow slab bridges and the existing repair and reinforcement technology,makes a detailed analysis of the causes of the diseases of hollow slab bridges,and compares the existing commonly used reinforcement methods from the two aspects of the reinforcement principle and technical characteristics,demonstrates the effectiveness of the pre-stressed carbon fiber plate as the ultimate bending capacity and bending stiffness reinforcement program of too high prefabricated hollow slab girders,and accordingly puts forward the theoretical analytical process of the formulation of the reinforcement parameters,and performs stress and deflection checks based on two assumptions,which ensures the applicability and reliability of the program.
