摘要
重力坝泄水建筑物水力计算是重力坝设计中非常重要的内容。本文系统地归纳了表孔、中孔、底孔在各种条件下的过流能力计算及水面线计算等方法，同时指出水力设计中应注意的问题，本文还对部分文献中有关计算公式中的错误作了更正。本文可供初参加设计工作的年轻工程师参考。
The hydraulic calculation for the water discharge structure of the gravity dam is a very important part in the design of a gravity dam. This article systematically summarises the calculation of overflow capacity of surface orifice, center orifice and the bottom orifice under various conditions along with the calculation of water surface profile, etc., and at the same time points out the notable problems in the hydraulic design. In some references, this article also corrects some errors in related calculation formulas.. This article can provide reference for the young engineers who just participate in the design work.
