摘　　要：长江中游枝江～江口河段为典型的沙卵石河段,其航道条件受诸多因素的影响。通过定床敏感性试验,分析了下游水位下降与洲滩冲刷变形对航道条件的影响,并进一步探讨了河段的治理思路,为河段的航道治理提供了依据。Zhijiang-Jiangkou section at the midstream of the Yangtze River is the typical sand and gravel section of the river,and its waterway conditions are effected by multiple factors.Through the bed sensitivity tests,the influences of the dropping of water level and erosion of shoals on waterway conditions are analyzed,and the regulation idea of the section are discussed.It provides a basis for waterway regulation of the section.

关 键 词：长江中游 敏感性试验 水位下降 洲滩 冲刷 治理
