摘要
烂沙洋潮流通道是江苏岸外辐射沙脊群内一条涨落潮流速大的潮流通道 ,利用其天然深水航道 ,可建设深水大港。为论证烂沙洋潮流通道的稳定性 ,在实测资料的基础上结合多种研究分析方法主要包括遥感影像分析、地理信息系统、沉积物粒度、主元素分析及水动力条件分析等对该地区进行了综合调查研究。研究结果表明 ,烂沙洋潮流通道从整体上讲是一条稳定的潮流通道 ,沉积动力条件较稳定 ,适宜建港 ,但在建港时仍需慎重地采取必要的工程措施以减轻西太阳沙北侧周期性冲刷现象。
Lanshayang tide channel is a major tide channel in radial submarine sand ridge system offshore Jiangsu Province where flood and ebb flow is strong. For making use of the deep-cut channel for buiding up a harbor. the stability of Lanshayang tidal channel is comprehensively studied based on the data from investigation and used manifold methods including remote sensing images analysis, geography information system, sediment grain size, principal element determination, hydrodynamics analysis and so on. The conclusion are as follows: Langshayang tide channel is a stablized tide channel which fits to build up a harbor, but some necessary engineering must be implimented carefully to reduce periodic erosion on its flanks.
