Abstract:

This research focused on the water flow that passes over supports of a bridge such as piers and abutments, observing the effect about its behavior when facing these structures, gotten by the non-destructive technique called particle image velocimetry. A scale model was used that represented a bridge which was formed by a circular pier in the center and two wing wall abutments on the banks, then it was placed in a hydraulic channel over a top view, in order to have information on vector patterns of high velocity turbulent flow. With this, it was possible to determine the critical areas of turbulence for this particular model, due to obstruction of both structures for pier and abutment, thence be able to propose changes in their geometry, alleviating these areas and thereby also reducing the probability of theorical bottom scour.
