摘　　要：三门峡水库运用初期形成的高滩深槽库区冲淤形态以及适当的泄流规模,为其蓄清排浑运用创造了条件。三门峡水库高滩深槽形成的过程是滩槽同步淤积抬升后主槽再冲刷下降。影响潼关以下库区主槽容积的主要因素为入库水沙条件、坝前运用水位和水库的泄流能力,当水库未发生滞洪壅水时,来水量的多少对主槽容积变化起主要作用。The bed morphology of high flood plain with deep channel in Sanmenxia Reservoir formed in its initial operation stage and the adequate flow discharging capacity has provided possibility for the operation mode of storing clear and releasing muddy. The forming process of high flood plain with deep channel includes tow stages, the synchronous silting and raising the flood plain and channel and then the solo scouring in and drop of the channel. The main factors influencing the storing capacity of the main channel of the reach below Tongguan include the incoming flow and sediment condition, the water stage and the flow discharging capacity of the dam. When there is no flood detention occurring in the reservoir, the total incoming water quantity has predominant impact on the storing capacity change of the main channel.
