| 摘 要： | 北江白石窑枢纽坝下变动回水区是北江中游重要的碍航浅滩.整治前,航槽水浅,船舶须减载或等水航行,塞船现象常有发生,维护水深仅在0.8～1.0 m,甚至断航现象时有发生,实施航道整治工程十分必要.为达到Ⅲ级航道标准,本文在分析浅滩的演变特点基础上,开发了河工模型,充分利用前整治建筑物,以因势利导为原则,利用挖槽、整治丁坝和疏浚等工程措施,对2个Ⅲ级航道整治方案进行对比分析,提出整治方案.从分析结果来看,此河段达到2.5 m×60 m的航道尺度是切实可行的. |

| Abstract: | The fluctuating backwater area under the dam of Beijiang Baishiyao water conservancy is an importantnavigation obstacle shoal to the middle of North River. Before waterway regulation engineering, the depth of waterway isshallow, so ships must reduce the load or delay sailing. Ship jam often occurs and water depth keeps only between 0.8~1.0 m.Even suspension of shipping occurs from time to time, so waterway regulation engineering is necessary. In order to achieveClass-III channels, this paper analyzes the characters of the evolution of these shoals, develops a river work model,takes full advantage of the regulating structures and makes the best use of the general trend, and takes appropriatemeasures to analyze the two waterway regulation schemes of Class - III channels, then proposes regulation scheme.According to the analysis result, it is feasible for the reach to achieve the waterway scale of 2.5 m×60 m. |
| Keywords: | waterway regulation engineering shallow fluctuating backwater area sediment erosion and depositionregulation measure |
