摘要： 消能防冲的设计是值得重视的问题,它关系到建筑物的安全及下游河床河岸的稳定。闸下冲刷破坏较普遍, 消能防冲设计条件选择不当是原因之一。通过1??50的水工整体模型试验,对钻根枢纽泄洪冲沙闸的布置进行了 深入的试验研究,不仅较好地解决了泄洪消能问题,简化了结构布置,而且节省了工程量,改善了流态和冲坑形态。

Abstract: The design of energy dissipation and erosion control is worthy of attention which relates building＇s security and the stability of river bed and river bank. The unreasonable determination of the design condition of energy dissipation and erosion control might be one of the key reasons for the scouring commonly occurring behind sluices. Through the experimental study carried out on a scale of 1 ： 50 solid hydraulic model for Zuan＇gen hydro project, the arrangement of the flood outlets is studied further, which has not only resolved the problem of flood energy dissipation, simplified the structural arrangement, reduced construction quantities but also improved the flow regime and the shape of scouring hole.

Key words: hydro project , energy dissipation and erosion control , hydraulic model test , comparison of projects ;
