The discussion presents results derived from a physical scale model of a plunge pool, downstream of a ski-jump dam spillway. The maximum uplift force is recognized to be produced by the difference in mean pressure between the upper and lower faces of the slabs, as evidenced by the authors, with the addition of the maximum differences in the instantaneous fluctuating pressure. In general, even when the fluctuating uplift forces are small compared with the mean value, their contribution should be considered in the slab equilibrium condition, at least for a safer design.

Abstract

The discussion presents results derived from a physical scale model of a plunge pool, downstream of a ski-jump dam spillway. The maximum uplift force is recognized to be produced by the difference in mean pressure between the upper and lower faces of the slabs, as evidenced by the authors, with the addition of the maximum differences in the instantaneous fluctuating pressure. In general, even when the fluctuating uplift forces are small compared with the mean value, their contribution should be considered in the slab equilibrium condition, at least for a safer design.
