坝内水电站空腹重力坝是一种特殊坝型,自50年代起,国内外就开始了这种坝型的研究和实践;在国内,清华大学最早提出了腹拱式空心重力坝这种新坝型,并进行了富有成果的研究;天津大学等也较早地进行了坝内式空腹重力坝的静力与动力特性的研究。国内已建成上犹、凤滩、枫树坝、石泉以及岩屋潭等水电站的大坝都属于空腹重力坝的类型。我国拟建的、位于高山峡谷、泄洪量大的一些大型水利枢纽的工程设计中,也多以此种坝型做为重要的比较方案;同时也是国家在水电方面长远科研规划中的
Dam within the fast-growing gravity dam hydropower station is a special type of dam, since the 1950s, both at home and abroad began this kind of dam-type research and practice; in China, Tsinghua University first proposed abdominal arch hollow gravity dam of this new dam Type, and carried out fruitful research; Tianjin University, also earlier carried out dam-style fasting gravity dam of the static and dynamic characteristics of the study. Dams built in Upper Utah, Fengtan, Maple Dam, Shiquan and Yanwu Lake are all types of fast-moving gravity dam in China. In the project design of some large-scale water conservancy hubs in our country, which are located in alpine gorges and have large flood discharge capacity, we also use this type of dam as an important comparison plan. At the same time, it is also a long-
