摘要
三峡升船机具有上游水位变幅大、下游水位变率快的特点,为保证船厢与工作门准确对位,升船机闸首工作门必须根据上下游水位变化不断调整门位。文章分析升船机闸首工作门在不同门位对应设计通航水位的临界水位附近变化时,升船机可靠运行的极限水位和最高挡水水位,为升船机安全运行提供理论依据。
The Three Gorges shiplift is characterized by large variation of upstream water level and fast variability of downstream water level.In order to ensure the accurate alignment of the ship chamber with the working bay gate,the gate must be adjusted according to the upstream and downstream water level changes.This paper analyzes the limit and the highest water-blocking water level under which the shiplift can operates reliably when the bay gate is positioned around the designed critical water levels related to different gate positions,to provide a theoretical basis for the safe operation of the shiplift.
