连云港区25万吨级航道和徐圩港区5万吨级航道常年回淤观测与研究

Observation and research on the perennial channel siltation of Lianyun Port 250,000 DWT waterway and Xuwei Port 50,000 DWT waterway

连云港港30万吨级航道一期工程自建设期开始分阶段、分航段开展了回淤观测。连云港区25万吨级航道和徐圩港区5万吨级航道常年回淤观测表明,航道实际回淤情况好于预期,其中旗台防波堤口门段减淤效果十分明显。结合底质采样、地形测量、风浪资料,利用数模计算,进一步深化了对航道回淤规律和回淤机理的研究,为连云港港30万吨级航道二期工程研究设计提供了技术支撑。

Channel siltation observation has been carried out since the construction period of the first phase of the300,000DWT channel of Lianyungang Port.It is found that the situation of channel siltation is better than expected by the observation and research on250,000DWT waterway of Lianyun port and50,000ton of Xuwei Port.Siltation reduction effect at the entrance section of Qitai breakwater is very obvious.Combination of sediment sampling,topographic survey,wind and wave data,using mathematical model calculation,the study of the laws and the mechanism of the channel siltation are further deepened.It can provide the technical support for research and design of300,000DWT channel phaseⅡproject of Lianyungang Port.
