射阳港进港航道工程导堤堤头冲刷试验研究

Research of Enter the Port Sea-route Project Reflected Port Head Guide Dike Scouring Test

采用潮流定床模型和局部动床模型,研究了射阳港进港航道工程潮流特征和导堤堤头冲刷问题。试验结果表明:工程区域内潮流特性发生显著变化,堤头扰流流速较大,悬沙分布和海床也相应变化,堤头海床会形成范围深度和较大的冲刷坑,设计防护设施坍塌,需对防护方案进行进一步优化,以确保建筑物结构的安全。

Adopting an fixed-bed wide model and local movable bed model,the local scour of head-bank erosion of the sheyang port approach channel project diversion dike were studied.The results show that the tidal phase of project area was significantly change and velocity of the corss-flow around the heads was large.Distribution of suspended sediment and seabed were corresponding changed.Greater scope and depth scour was form around the heads.Further optimize of protection facilities were need to ensure the buildings structural safety because of the designed protection facilities was collapsed.
