Determination of the Hydrodynamic Load on an Inundated Bridge Deck by Measurements Performed on a Physical Model

Original language description

The paper describes the options for the determination of the hydrodynamic load on an inundated bridge deck based on experimental measurements performed on a physical model. The motivation for resolving the given issue came from real-world cases where options are limited as regards modifications to the level of the bridge superstructure and the road in the immediate surroundings of the bridge. Under these conditions, the given bridge should be evaluated in greater detail from the aspects of both flood discharge capacity and the potential hydrodynamic load if water flow inundates the bridge structure. The subject of the experimental measurements was the determination of what are known as drag, lift and moment coefficients, which are essential for quantifying individual components of hydrodynamic load. The research focused on a special type of load-bearing bridge structure with minimized structural height designed for railroad tracks. Before the actual measurements took place it was necessary to determine a set of measuring equipment that would be economically acceptable for the purposes of research and engineering practice. The results of our experimental measurements confirmed that the selected specific bridge deck shape has a clear and significant influence on the drag coefficient values obtained. The lowest values were achieved by the bridge deck shape with chamfered edges. The correctness of the achieved results was verified by comparison with published domestic and foreign papers on the given field. The achieved results enable the determination of the hydrodynamic load of the examined types of load-bearing bridge structures during the reconstruction or building of new bridges. Other fundamental uses are expected, e.g., in the verification of numerical hydrodynamic models.
