飞来峡水利枢纽溢流坝消能防冲设计

Design of Energy Dissipation and Erosion Prevention for Spillway of Feilaixia Project

本文介绍了深尾水、大淹没度条件下消能工形式的选择及试验研究，从而选定了适于本枢纽的面流消能工形式。对闸室的不利流态通过闸门调度来解决；隔墙在水流的脉动紊动作用下是否会引起振动作了分析。

This paper presents the selection and experiment on types of energy dissipators under condition of deep tailwater and large submergence. Thus the dissipator of surface current type has been chosen for this project.Unfavorable flow regime in gate chamber is solved by regulation of gate. Whether the partition wall vibrates under the effect of flow PulSation and turbulance or not is analized.
