港航施工中的回淤问题和对策研究

Research on the Problems and Countermeasures of Back Siltation in Port and Shipping Construction

以喀麦隆克里比深水港二期工程项目为例,论文分析泥沙来源以及回淤随时间、水深、航道位置变化的一般规律,并针对影响回淤的4个因素,包括水文地质因素、极端气候因素、挖泥船溢流因素及施工期因素,提出相应的全面的治理方案,如完善项目前期规划,控制挖泥船溢流时间,制定防淤减淤措施,合理选择疏浚清淤设备等。

This paper takes the second phase of the Kribi Deepwater Port Project in Cameroon as an example,analyzes the source of sediment and the general laws of back siltation over time,water depth,and channel location,and in view of the four factors affecting back silting,including hydrogeological factors,extreme climate factors,dredger overflow factors and construction period factors,a relevant comprehensive treatment plan is put forward,such as improving the project planning,controlling the overflow time of dredger,developing measures to prevent and reduce silt,and selecting dredging equipment reasonably etc.
