拱坝是水利工程中最常用的坝型之一。与其他混凝土坝相比,它具有大量节省材料和很大超载能力等优点,所以,在我国大型水电建设中,拱坝方案常常是挡水建筑物的最佳的选择。我国是一个多地震的国家,适合修建高坝大库的地方往往是高烈度地震区,为了迅速发展我国水力发电事业,必须着重研究高烈度地区建造高坝的技术,而拱坝在地震时的动力分析方法是其中的一个重要课题。 Arch dam is one of the most commonly used dam types in hydraulic engineering. Compared with other concrete dams, it has a lot of advantages such as material saving and overloading capacity. Therefore, arch dams are often the best choice for retaining structures in China’s large hydropower construction. China is a country with many earthquakes. The places suitable for constructing high dams are often high-intensity seismic areas. In order to rapidly develop China’s hydropower industry, we must focus on the research on the construction of high dams in high-intensity areas. When the arch dam is in an earthquake Dynamic analysis is one of the important topics.
