摘　　要：山区航道高水头通航建筑物多采用船闸、升船机、隧洞和中间渠道组合布置的形式。多种通航建筑物组合布置时,各通航建筑物的通过能力相互制约和影响,计算较为复杂。结合工程实际,在通过能力计算中,分析了通过各建筑物时间的匹配性及其对通航效率的影响,指出在组合布置通航建筑物时,应以船闸或升船机1次运行时间为基础,复核计算通航隧洞、辅助闸门等其他通航建筑物的1次运行时间是否小于基础时间,当大于基础时间时,应合理调整组合形式、布置形式和建设规模,成果可为类似工程提供参考。High head navigation buildings in mountainous waterways are often arranged in combination with ship locks,ship elevators,tunnels,and intermediate channels.Due to the mutual constraints and influences on the carrying capacity of various navigation buildings,their calculations are relatively complex.This article combines engineering practice and analyzes the matching of time passing through various buildings and its impact on navigation efficiency during the calculation of passing capacity.It is pointed out that when arranging navigation buildings in combination,the one-time operation time of the ship lock or ship lift should be used as the basis to recheck and calculate whether the one-time operation time of other navigation buildings such as navigation tunnels and auxiliary gates is less than the basic time.When it is more than the basic time,the combination form,layout form,and construction scale should be reasonably adjusted.The achievements can provide reference for similar projects.
