Rigid Connection Widening Design and Load Test of Concrete Hollow Slab Bridge
Bridge widening technology can effectively improve the traffic capacity of existing bridges and has been widely used in bridge reconstruction.In order to improve the transverse connection performance of the concrete hollow slab widening bridge,this article proposes to use rigid connection structure instead of hinge joint connection based on actual engineering background,and optimizes the design of rigid connected hollow slab.The overall mechanical performance of the widened bridge is evaluated through the field load test.The results show that the transverse connection of the rigid connection bridge is reliable and can avoid the diseases in the later stage of hinge joint connection.The overall bearing capacity and stiffness of the widened bridge meet the requirements of the design load.The research results can provide reference for bridge widening design.
