摘　　要：滇中引水工程观音山倒虹吸长达9.8 km,输水流量达100 m^(3)/s,采用3根4.2 m内径的压力钢管输水。在满足输水流量的同时需要保证倒虹吸进口一定的淹没深度,避免进口掺气等不利水力现象。为简化调度运行提出不同输水通道数匹配输水流量级别、节制闸与溢流堰联合控制的方式,实现出口节制闸仅全开或全关两种运行状态。Guanyinshan inverted siphon of Central Yunnan Water Diversion Project is 9.8 km long,with a water conveyance flow of 100 m^(3)/s.The inverted siphon is composed of three 4.2 m inner diameter steel penstocks.While meeting the water delivery flow,it is necessary to ensure a certain submergence depth at the inverted siphon inlet to avoid adverse hydraulic phenomena such as aeration.This paper proposed that different number of conduits match different delivery flow,and the joint control of the sluice and overflow weir,to realize the two operation states of the outlet sluice:fully open or fully closed.
