Reducción de la socavación local en estribos cortos y verticales de puentes.

In this work is described a research project, which central objective was to reduce scouring depth in shorts and vertical abutments of bridges, so in this it was analyzed at trough of a physical model reduced, the scouring depth that generate an water flow in a system performed by a short and vertical abutment of bridge, in a sand channel of hydraulic engineering laboratory of ESIA Zacatenco United, in Mexico; the abutment was modified in his geometry (with wings to 45, 30 y 20º), in order to determine experimentally its influence in local scouring that was generated, with some flow condition; and in the way of essay‐error to reduce the local erosion. In this project, the local erosion depth generated by the original abutment was reduced in a 98 %. [ABSTRACT FROM AUTHOR]
