Research on the Anti-collision Performance of Temporary Harbor Parking Belt Barrier Reconstruction on the Expanded and Reconstructed Expressway
In order to make the concrete prefabricated block structure of the temporary harbor parking belt on the expanded and reconstructed expressway reach the A-level protection level,the temporary harbor parking belt is reconstructed.The reconstructed structure is composed of concrete prefabricated blocks,three wave beam plates and connecting members.Through the simulation analysis of the three(A)level collision conditions specified in the Standard for Safety Performance Evaluation of Highway Barriers(JTG B05-01-2013),the anti-collision performance is verified.In order to judge the effect of the reconstruction method adopted in this paper,the simulation analysis is carried out.By analyzing the simulation results,it can be seen that after the reconstruction is completed,the anti-collision performance of the parking belt barrier meets the specification requirements.
