摘　　要：为探明城陵矶—武汉河段的航道水深资源,根据每一水道的河相关系参数对研究河段进行区段划分,并采用稳定航深估算法对不同区段的航道最大稳定航深进行计算,进而确定研究河段的航道最大水深。结果表明:研究河段依据水道河相关系参数变化规律,可自上游至下游分为仙峰水道—新堤水道、石头关水道—簰洲水道、水洪口水道—白沙洲水道区段;这3个区段在98%设计通航保证率流量、航宽200 m下的航道最大稳定水深自上而下分别为6.133、11.268和6.433 m,故城陵矶—武汉河段在200 m规划航宽下基于自然禀赋的最大稳定航深为6.1 m。To explore the water depth resources of the channel in Chenglingji to Wuhan reach,the study section is divided according to the river phase relationship parameters of each channel.The maximum stable channel depths of the channels in different sections are calculated by the stable channel depth estimation method to determine the maximum water depth of the channel in the study section.The results show that the study section is based on the change rule of the river phase relationship parameters of the channel,it can be divided into three sections from upstream to downstream,such as Xianfeng waterway to Xindi waterway,Shitouguan waterway to Paizhou waterway,and Shuihongkou waterway to Baishazhou waterway.The maximum stable water depths of the channels under 98%design navigation guarantee rate and 200 m navigation width of the three sections are 6.133 m,11.268 m and 6.433 m respectively from upstream to downstream,so the maximum stable channel depth of Chenglingji to Wuhan reach under 200m planned channel width is 6.1m.
