拱坝是一种经济和安全度较高的坝型,在国外有较长的建设历史,修建的数量也较多,技术发展已达到较高的水平。我国水能资源丰富,开发条件优越,今后如能积极发展拱坝技术,因地制宜地选用这种坝型,必将有利于加快我国水电建设。为此,特将国外的拱坝建设及其发展水平综述如下,以供参考。 Arch dam is a type of dam with high economic and security. It has a long history of construction abroad and a large number of construction projects, and the technical development has reached a higher level. China is rich in hydropower resources and enjoys excellent conditions for development. In the future, if we can actively develop arch dam technology and choose this type of dam according to local conditions, it is bound to speed up hydropower construction in China. To this end, especially the construction of the arch dam abroad and its level of development are summarized below for reference.
