对泄水建筑物消能工形式的选择是水能资源开发中的重要环节。某水利工程输水洞下游消能塘采用冲击墩、台阶与消能塘联合消能的方式进行消能设计，为研究三种消能工的消能效果，通过模型试验对其消能工的消能率进行对比分析，共进行两种工况的消能方案计算，分别为冲击墩与消能塘联合消能、冲击墩与台阶及消能塘三者联合消能。计算结果表明，三者联合消能方式可以有效消除输水洞水流入塘时的能量从而减轻水流对下游河床及岸边的冲刷，达到保护工程安全的目的。
對洩水建築物消能工形式的選擇是水能資源開髮中的重要環節。某水利工程輸水洞下遊消能塘採用遲擊墩、檯階與消能塘聯閤消能的方式進行消能設計，為研究三種消能工的消能效果，通過模型試驗對其消能工的消能率進行對比分析，共進行兩種工況的消能方案計算，分彆為遲擊墩與消能塘聯閤消能、遲擊墩與檯階及消能塘三者聯閤消能。計算結果錶明，三者聯閤消能方式可以有效消除輸水洞水流入塘時的能量從而減輕水流對下遊河床及岸邊的遲刷，達到保護工程安全的目的。

It’s important to choose an appropriate type of energy dissipation in discharge structures .Here ,three kinds of dissipaters ,which were shock pier ,stairs and stilling basin were designed to dissipate energy in the downstream of the water conveyance tunnel in a hydraulic project .To study the effect of the three energy dissipaters ,model test was adopted to research the energy dissipation rate in this paper .Two conditions of energy dissipations were calculated ,including the combination of shock pier with stilling basin and the combination of shock pier ,stairs and stilling basin .The test results prove that the combination of the three energy dissipaters is effective in eliminating energy of flood flows when they reach the stilling basin of the water conveyance tunnel ,thus reducing the scour to the waterbed and river banks in the down-stream and protecting the project for it to operate safely .
