摘　　要：变动回水区河段设计最低通航水位确定是目前山区航道整治工程中经常遇到的问题。以广西绣江交口电站的变动回水区河段为例,分析了变动回水区的水沙特性,分别利用水位、流量样本及不同方法计算与分析本河段的设计水位,提出了变动回水区河段设计最低通航水位的确定方法。In regulation works of mountainous channel, determination of designed lowest navigable water level of reach with fluctuating backwater area is a common problem. Taking the reach with fluctuating backwater area in Jiaokou Hydroplant in Xiujiang River, Guanxi Zhuang Autonomous Region for instance, this paper analyzes the water-sediment characteristics of the fluctuating backwater area, calculates the design level of this reach with samples of level and discharge, etc., and propounds the determination method for the designed lowest navigable level of reach with fluctuating backwater area.

关 键 词：变动回水区 设计最低通航水位 水沙特性
