Research Review on Debris Flow Impact on Bridge Structure
In order to promote the in-depth study of the impact of debris flow on bridge structure,important research progress in this field in recent years is reviewed,and the four aspects of research methods,debris flow impact force,bridge structure response and structural disaster prevention and mitigation are systematically reviewed.The analysis shows that:1)Indoor experiments and numerical simulations are currently the main methods for studying the impact of debris flows on bridges.The two complement each other and provide strong support for further research on the interaction between debris flows and bridges;2)The dynamic response of bridge structures is related to the rheological parameters of debris flow and the impact force of debris flow,and the three have a certain mapping relationship;3)The coupling mechanism and comprehensive impact of debris flow slurry and large rocks on bridges have not been clarified,which is one of the key research directions in the future;4)Active and passive protective measures can effectively weaken the impact force of debris flows and reduce bridge risks.The relevant conclusions can provide reference for the clear research on the impact of debris flow on bridge structures.
