摘要
采用局部正态模型对长江南京以下12.5 m深水航道一期工程白茆沙水道工程进行了局部冲刷试验研究,试验结果表明:1)白茆沙水道工程S1丁坝、S2丁坝、S3丁坝以及南侧围堤堤头等附近易产生较严重的局部冲刷,应重点防护;2)优化方案不仅防护效果好,而且护排布置合理,能同时满足工程安全和节约投资的需求。
Local scour in Baimaosha channel project of the first phase of the Yangtze River deep water channel project from Nanjing areis studied by local normal model. The results show that: 1) S1 groyne, S2 groyne, S3 groyne and the head of south polder dike, etc. are positions prone to appear significant local scour in Baimaosha channel project, and thus need to focus on protection; 2) Optimization scheme is not only effective to prevent local scour, but also scientific and rational in layout design of flexible mattress, thus can meet the needs of engineering safety and conservation investment.
