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.

在同一坝址下进行水电枢纽建设,挡水构筑物的高度是一个受众多因素影响的关键指标。从挡水大坝地震动响应变化的角度,对某工程挡水构筑物三种设计坝高方案在静动力叠加工况下的响应进行了分析比较。结果表明,随着坝体的增高,拱坝的自重和库水压力不断增大,但其地震动响应并非都随坝体的增高而增大,算例中拱坝上游面梁向和拱向压应力随着坝体的增高而增大,下游面梁向压应力随着坝体的增高而减小,拱向压应力随坝体的增高呈先减后增的趋势,正向位移和开度则随着坝体的增高呈先增后减的趋势。该研究结果可为挡水构筑物的相关设计提供参考。

在同一坝址下进行水电枢纽建设,挡水构筑物的高度是一个受众多因素影响的关键指标。从挡水大坝地震动响应变化的角度,对某工程挡水构筑物三种设计坝高方案在静动力叠加工况下的响应进行了分析比较。结果表明,随着坝体的增高,拱坝的自重和库水压力不断增大,但其地震动响应并非都随坝体的增高而增大,算例中拱坝上游面梁向和拱向压应力随着坝体的增高而增大,下游面梁向压应力随着坝体的增高而减小,拱向压应力随坝体的增高呈先减后增的趋势,正向位移和开度则随着坝体的增高呈先增后减的趋势。该研究结果可为挡水构筑物的相关设计提供参考。

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.
