摘要

The response of a grid gate to static and dynamic loads was investigated, emphasis being given to the effects of streamline and turbulent flows. The grid gate is an alternative solution to parallel surge barrier studies for the Schaldt area in the Netherlands. It exhibits an optimum flow distribution; a short stroke is required for the lifting system. Different scale models were investigated in water and wind tunnels. The strong vibrations observed when the gate was open, which are clearly reinforced by coupling effects, can be eliminated by optimum design together with vibrations occurring at a 60% opening. The grid gate appears to be a good solution to retain a discharge well distributed over the height of a water course.
