Abstract

Abstract: The water level fluctuation transferring rules of the TGP shiplift downstream channel between approach entrance and chamber were simulated by 2D numerical model in various downstream water level, fluctuation amplitude and cycle. The relation of the TGP shiplift downstream water level fluctuation between approach entrance and ship chamber was established. Based on the water level fluctuation transfer relation, a new security warning measurement was proposed by monitoring approach entrance water level to reduce the risk of the TGP shiplift chamber docked with downstream approach in unsteady flow.

Key words: waterway engineering, shiplift, chamber dock, approach channel, security warning

摘要： 通过数学模型计算分析了不同下游水位、不同波动幅值和波动周期条件下，三峡升船机船下游引航道承船厢位置附近与口门区之间水面波动的传递规律，建立了三峡升船机下游引航道口门区与承船厢位置的水位波动变化关系；提出了利用口门区水位波动监测资料进行船厢对接实时预警的新方法，降低了枢纽非恒定水流变化引起的升船机船厢运行对接安全风险。
