Method for evaluating flood resistance of superstructure of simply supported beam bridge

Abstract

The present application relates to the technical field of bridge flood resistance evaluation, in particular to a simple supported beam bridge superstructure flood resistance evaluation method.The simple supported beam bridge superstructure flood resistance evaluation method comprises the following steps: obtaining parameter information of the simple supported beam bridge to be evaluated; substituting the parameter information into a flood resistance index relationship formula for calculation, and obtaining a calculation result, wherein the flood resistance index relationship formula comprises a slide resistance index relationship formula and an overturning resistance index relationship formula; and evaluating the flood resistance of the simple supported beam bridge superstructure according to the calculation result.The flood resistance evaluation method provided by the present application solves the problems of low safety and high cost in bridge underwater detection, can provide bridge superstructure risk degree evaluation results and reports in a timely manner, helps to find potential problems and take preventive measures in a timely manner, improves the sustainability and disaster resistance of bridges, and thus ensures the safety and stability of transportation.
