| 中文摘要: |
| 针对三峡水库变动回水区虾子梁滩段航道在枯水期面临的弯、窄、急、险等碍航问题，进行养护疏浚工程的研究与实践。通过收集大量历史实测资料，对比分析多年等深线、冲淤变化等情况，得出该滩段整体表现为缓慢持续淤积的趋势，结合该河段的航道条件和水情特点，对施工设备及施工水位进行比选，制定合理的养护疏浚方案。工程实施结果表明，养护疏浚工程改善了航道条件，拓宽可通航水域，减小船舶操作难度，有效保障了航道畅通和通航安全。 |
| 英文摘要: |
| Research and practice on maintenance and dredging engineering are conducted to address the navigation obstacles faced by the Xiaziliang shoal section of the Three Gorges Reservoir’s variable backwater area during dry season,such as bends,narrowness,rapidity,and danger.It is found that the overall trend of this beach section is slow and continuous sedimentation by collecting a large amount of historical measured data and comparing and analyzing the changes in isobaths and erosion and sedimentation over the years.On the basis of the waterway conditions and water characteristics of this river section,the construction equipment and the water level are compared,and a reasonable maintenance and dredging plan is formulated.Implementation results of the project indicate that the maintenance and dredging project can improve the conditions of the waterway,expand navigable waters,and reduce the difficulty of ship operation,thereby ensuring the smoothness and safety of the waterway. |
