Research on Hydrology Design and Checking of Bridges in Small and Medium Watersheds

Abstract:

In order to reduce the flood disaster of bridges in small and medium watersheds, a hydrology design and checking method, which was based on flow influence line, was put forward. The basic steps of this method are as follows: calibrate model by water marks and the corresponding rainfall series; calculate flow process line by loading rainfall series of design or checking frequency on calibrated model, and get design peak flow, design flood-peak stage, checking peak flow, checking flood-peak stage, etc; so hydrology design of new bridges and checking of existing bridges can be done. The results show that this method requires less parameter, and is convenient in practical application and reliable in calculation accuracy. Therefore, it is of great significance for new and existing bridges avoiding flood damages.
