Abstract

In order to improve the on-site construction efficiency of bridge concrete barriers,a prefabrication scheme for bridge concrete barrier installation was proposed.A structure scheme was developed by anchoring transverse steel bars at the bottom of prefabricated wall panels into the integrated cast-in-situ layer,adopting tongue-and-groove connections between adjacent wall panels,and optimizing the structural configuration and reinforcement of the panels.According to the requirements of the Level VI protection standard,full-scale impact tests using a large bus and a large truck were organized in turn.The results show that the prefabricated concrete bridge barrier can effectively withstand continuous impacts from both large buses and trucks.Its structural integrity and connection reliability meet the safety performance indexes,thereby verifying the feasibility of the prefabricated concrete bridge barrier scheme.
