连云港港30万吨级航道建设主要技术问题

连云港港30万吨级航道位于开敞海域,淤泥质浅滩宽广,航槽开挖厚度大,航道里程长,工程规模大,建设条件复杂,是开敞海域淤泥质浅滩深水航道的典型。通过研究基本解决了海床性质及岸滩稳定性、水动力泥沙条件、航道回淤、航道选线、航行安全性等主要技术问题,不仅为连云港港航道后续研究设计打下了坚实的基础,而且可供国内外其他淤泥质浅滩深水航道建设借鉴。对主要技术问题的研究成果进行系统总结。

Main technical problems in construction of Lianyungang port 300 000 DWT waterway

Lianyungang port 300 000 DWT waterway is a typical deep waterway in the mucky shallows of open waters characterized by large excavation thickness, long waterways, large engineering scale and complex construction conditions. By research, the nature of the seabed and beach stability, hydrodynamic sediment conditions, waterway sedimentation, waterway route selection, navigation security, and other major technical problems, are basically solved. The results not only lay a solid foundation for the follow-up study design Lianyungang port waterway, but also may serve as a reference for the construction of other mucky shallows deep water channel. The main technical problems are summarized.
