| 摘 要： | 枢纽下游河床遭受清水冲刷,河床下切、水位降落是普遍的规律,也是历来枢纽设计及航道整治中的重点和难点,文中针对闽江水口枢纽坝下水位降落幅度及河床地质条件,采用1:100正态物理模型与遥控自航船模相结合的研究手段,提出了若坝下水位降落幅度较小,且坝下河床冲刷已基本稳定,可采取潜坝或明渠及溢流坝方案治理;若坝下水位降落幅度较大,且坝下河床冲刷仍在继续,单纯解决通航问题可采取船闸改造或船闸加中间渠道方案治理。

| Abstract: | The scouring of rivebed below dam and fall in water level are not only the universal law,but also the difficult and important points in channel regulation and the design of hydro-junction.Based on the geological conditions of the river bed and drawdown range of the Shuikou Hydro-junction in the Minjiang River,a method of combining remote-controlled self-propelled ship model test with normal physical mode test with the scale of 1:100 is used in this paper.A submerged dam,open channel and overflow dam can be used if the water level decreased slowly.Otherwise,the ship lock with intermediate channel can be used to solve the problem. |
