In the construction of hydropower projects under the same dam site, the height of water-retaining structures is a key index affected by many factors. In this paper, the responses of three design dam height schemes of a water-retaining structure under static and dynamic superposition conditions were analyzed. The results show that although the dead weight and reservoir water pressure of the arch dam increase with the increase of the dam height, the ground motion response of the arch dam does not all increase with the increase of the dam height. In this calculation case, the beam compressive stress and arch compressive stress on the upstream surface of the arch dam increase with the increase of the dam height, the beam compressive stress on the downstream surface decreases with the increase of the dam height, and the arch compressive stress first decreases and then increases with the increase of the dam height, the forward displacement and openness first increase and then decrease with the increase of the dam height. The research results can provide a reference for the design of water-retaining structures.
