摘　　要：以三峡船闸为例建立槛上水深变化的理论计算模型,对上下游水位和最小槛上水深的关系进行分析,阐明最小槛上水深发生的特征.针对当前通航调度规程规定的部分特征水位情况,利用该模型对船闸槛上水深控制部位和最小值进行测算,为合理发布过闸船舶吃水控制标准提供理论依据.Taking the three gorges shiplock as example,this article establishes a theoretical calculation model of the water depth on lock sill,and analyzes the relationship between upstream or downstream water level and minimum water depth on lock sill.According to the model,the paper clarifies the characteristic of the minimun water depth taking place on the sill,and estimates the control station and minimun value of water depth on the sill of the lock,which can provide a theoretical basis for releasing the draft control standard of passing ships reasonably.
