摘　　要：在长江南京以下12.5 m深水航道一期工程白茆沙整治工程中,为实现"遏制不利趋势、改善航道条件"的整治目标,通过河床演变分析、数学模型计算、物理模型试验等途径确定了整治方案。通过多方案比选,项目采用软体排作为护底结构、抛石斜坡堤和构件堤作为导流结构的工程措施,研发一种新型护滩结构——主动式钩连体,并在工程中得到应用。In phase Ⅰ （ Taicang to Nantong section） of 12. 5 m deep-water channel project from Nanjing in the Yangtze River, to achieve the goal of ＂curbing adverse trends and improving channel conditions＂, we carried out riverbed evolution analysis, mathematical model calculation and physical model test and determined the regulation scheme at last. Based on a multi-program comparison, we chose the flexible mattress, riprap embankment and component embankment as the engineering measures, and developed a new beach protection structure, i. e. the active hook, and applied it to the project.
