| 本文介绍了水口电站因泄洪与电站负荷调节引起的坝下往复波流对垂直升船机运行影响的水力学试验成果.在试验研究的基础上提出以下成果：承船厢与航道中影响波高值的因素；从电站调峰到承船厢内出现允许波幅所需时间T1及到达稳定水位所需时间T2；承船厢、航道中可能出现的最大、最小水深；承船厢中最大、最小水重与超载情况；瞬时水面线、最大水面坡度和流速.以上成果为垂直升船机的安全运行提供了依据。 |
| 英文摘要: |
| The effects of unsteady flow downstream the hydropower station dut to flood discharge and load regulation on the operation of ship lift are studied in a hydraulic model test. The factors affecting the wave heights in ship compartment and navigation channel, the time period from peak power regulation to the arise of maximum wave height and the duration for water surface reaching a steady level are investigated. Furthermore, the probable maximum and minimum water depths in ship compartment and in navigation channel, the maximum and minimum water weight in compartment as well as the maximum water surface slope and velocity are studied. |
