摘　　要：为避免淮河洛河洼采砂船损伤1000kV淮南~南京淮河大跨越线路,本文通过采砂船现场测量、生产厂家调查、砂层勘测等方法,结合采砂需求,对洛河洼采砂船高度进行分析,确定淮河洛河洼1000kV大跨越线路对最高通航水位的净空高度取65m,近年的运行情况表明,未发生因采砂船逃窜导致的导线损伤事故。In order to avoid damage to 1000 kV Huainan-Nanjing Huai River Long Span Transmission Line caused by sand dredger in Luohe depression of Huai River, this paper analyses the height of sand dredger in Luohe depression by means of on-site measurement of sand dredger, investigation of manufacturer and survey of sand layer, combined with sand dredging demand, and determines that the clearance height of 1000 kV Long Span Transmission Line in Luohe depression of Huai River is 65m for the highest navigable water level, and its operation in recent years. The results show that there is no wire damage accident caused by the escape of sand dredger.
