| 摘 要： | 阀门水力学问题一直是高水头船闸设计的关键技术难点。以在建的大藤峡单级船闸为例，基于国外省水船闸工作原理，提出带两级蓄水池船闸方案。输水系统水力学初步计算表明，阀门工作水头削减20.125 m，省水率可达到48.76%。与单级船闸方案比较结果表明，该输水系统形式因水头大幅降低，设计和建造均大为简化，在山区河流高坝通航领域以及兼顾发电与农业灌溉用水紧张的情况下，应用前景非常广泛。

| Abstract: | Valve hydraulics problems are the key technical problems in single-step locks with high head.The lock with two levels of water-saving pools is carried out to solve the problem in Datengxia lock,based on the theory of water-saving shiplock abroad.It is concluded that the water-saving shiplock can reduce the work head with 20.125 meters and the water-saving rate is 48.76%.Comparing with the single-step locks,it can simplify the filling and emptying system because of the lower head.Besides,the water-saving shiplock has a broad application prospect in high dam navigation which considers both power and agricultural irrigation. |
