摘要： 三峡电站汛期调峰对两坝间通航条件影响试验研究成果表明,三峡电站汛期调峰具有流量大,流量变幅大,水位波动强等特点,电站调峰过程中两坝间河段沿程流速、比降较枯水期调峰显著增大,对航运的影响更为明显,在三峡电站日均下泄流量10000~15000 m3/s时,两坝间河段的航行条件尚能满足万吨级船队的航行要求,但日均流量为20000 m3/s时,两坝间重点滩段的流速、比降,已接近或超过万吨级船队的允许值,船队上行十分困难.

Abstract: The Experiment study on influence of TGP regulation the peak flood to the navigational condition between two dams shows, the regulation peak has the characteristic with large discharge, widely discharge variation and water level fluctuant and so on. During the adjust peak, the velocity and slope during two dams are higher than low water evidently, the influence on navigation is obviously. When the released discharge diurnal average is between 10000 and 15000 m3/s, the navigation condition can meet the requirement of 10000 tons ship team, but when the discharge exceed 20000 m3/s, the velocity and slope at important bar between two dams are near or over the allowable value, the upward ship team sail difficultly.

Key words: TGP (Three Gorges Power Station), regulation peak flood, between two dams, navigational condition
