Research and Practice on Key Technology of Replacing Superstructure of Highway In-service Bridges
In recent years,with the rapid development of China's transportation infrastructure,the demand for in-service highway bridge repair and renovation has also increased,while in-service highway bridges are facing the problem of rising traffic volume and increasing renovation constraints day by day,and economic,efficient,green and environmentally friendly renovation solutions have become the core of in-service highway dilapidated bridge renovation.This paper combines engineering examples,considering the structural characteristics of the original bridge,the selection of the superstructure,substructure utilization of a systematic discussion,making full use of UHPC combined with the deck plate combination beam construction convenient and efficient to achieve the rapid re-placement of the bridge superstructure,and load test on the structure of the safety performance verification,the test results show that the structure of the static and dynamic load capacity performance is good.
