Abstract:

 

Infrastructural elements of bridges mounted in alluvial  stream beds are susceptible to scouring.  Decision-making for the type  and placement practice of relevant countermeasures to be implemented  against scouring action is based on investigation of the  characteristics of scour holes formed around piers and abutments.   This would also lead to the estimation of the safe depth of burial of  footings of bridge infrastructural elements.  Sets of experiments have  been performed to investigate time-dependent characteristics of scour  holes around cylindrical and square piers and vertical-wall abutments  under clear water conditions with uniform bed materials.  In the  course of the experiments, temporal variations in scour depth and  scour contours were measured.  Using this information, a number of  empirical relations were developed for temporal variation in  dimensionless scour surface area and scour hole volume.  The findings  of this study may provide useful information for the preliminary  design of armoring countermeasures around such infrastructural  elements.
