| 摘 要： | 为了改善工程区的流场分布，根据烟台西港区一期工程潮流数学模型试验的研究成果，针对引桥为透空和实体的结构形式，分析了工程建设对流场的影响，以及桥墩不同间距直至实体时工程海域流场的变化情况和对通航条件的影响，并对回转水域和停泊区的流速流向变化进行了对比分析。结果表明：桥墩间距在5～15m时，可以兼顾透流效果和掩护条件，满足工程要求。

| Abstract: | In order to improve the current field distribution for Phase 1 engineering of Yantai West Port zone,a tidal mathematic model was adopted to simulate the current field with different types of approaching bridge,open and solid structure.And influence of engineering construction on tidal current was analyzed,as well as current variety with different spacing of bridge piers and its influence on navigation condition.In addition,the changes of velocity and direction of turning water area and harborage were analyz... |
