摘要
重力坝下游泄洪消能设计和计算是重力坝设计的重要组成部分。本文系统地归纳和总结了各种消能方式的适用范围和水力计算方法，同时补充了我院近年来在大型水电工程中采用的“跌坎底流消能”构造实例和运用情况。本文可供初参加设计工作的年轻工程师参考。
The design and calculation of flood discharge and energy dissipation design at the lower reaches of a gravity dam is an important integral part of gravity dam design. This article systematically summarises and concludes the applicable scope of various energy dissipation methods and the hydraulic design methods and at the same time additionally introduces the construction example and operating condition of ＂step-down energy dissipation by tmderflow＂ which has been aoDlied by our institute in the lar^e-scale hydroelectric projects in recent years.
