WebIn addition to the above major forces acting on a gravity dam, forces caused due to silting in immediate vicinity of the upstream face (silt pressure) and due to the waves caused by strong winds blowing over the reservoir water may also be considered. Generally these types of forces are of theoretical significance only and easily ignored. WebApr 13, 2024 · The dam break wave impact on the bridge deck can be identified as two distinct scenarios according to whether the wave height is higher than the bridge deck top. The trend of the tsunami force is also different in different scenarios. The superelevation will significantly influence the tsunami forces acting on the box girder, with some exceptions.
