唐山港京唐港区沿岸建港前后潮汐、海流特性分析

摘要

Through the collection of observed data of tides and currents since the building of Jingtang port area in Tangshan Port, the tide characteristics in surrounding sea area and the current characteristics of different sea areas are analyzed. The analysis shows that the port construction has insignificant effect on tidal characteristics, along with the port construction, the construction of port structures and the resultant changes of the terrain, the flow field in the sea near the port is changed, but the impact on farther area currents is decreased gradually.%通过搜集唐山港京唐港区建港以来多次潮位、海流观测资料,对京唐港区附近海域潮汐特征以及港区不同海域的流场特点进行对比分析.分析表明:港口建设对潮汐特性影响不明显；随着港口建设,港口建筑物及其引起的地形变化改变了港区较近海域流场,对港区较远海域海流的影响逐渐减小.
