Abstract: This paper discusses and analyses the technical difficulties resulting from applying high-lift vertical ship lift to great amplitudes of headwater level and downstream stage of navigation high-lift dams in mountain rivers as well as downstream stage changes caused instantaneously by a regulating flood peak water plant. The relative principles and measures to solve them are also proppsed.

Key words: high-lift, vertical ship lift, amplitude of stage, hydraulic selfacting gate sill

摘要： 本文针对我国山区河流高坝通航上、下游水位变幅大,且调峰电站下游水位瞬时变率快的特点,对高水头垂直升船机由此而造成的技术难题,提出了相应的设想和措施,并对这些设想和措施进行了分析,同时提出了尚待研究和解决的问题。
