人工措施改善大连港鲇鱼湾港区建港水文条件研究

On artificial measures to improve hydrologic condition for port construction of Nianyuwan harbor area in Dalian port

大连港鲇鱼湾港区沙坨子导流堤工程建设前,22#原油泊位北端横流较大;17#～21#泊位泊稳条件较差.为了改善鲇鱼湾港区建港水文条件,采用潮流数学模型试验、物理模型试验的手段对改善流场的方案进行系统研究,同时结合波浪整体物理模型试验对改善泊稳条件也进行了分析,综合比较潮流和波浪两个因素,对沙坨子导流堤工程的平面布置、水工方案进行全面总结,分析探讨人工措施改善建港水文条件的整体思路、研究方法和手段,为其他类似工程提供参考.

Before the construction of Shatuozi diversion dike in Nianyuwan harbor area of Dalian port, the cross-flow of No. 22 berth is larger and mooring condition of berths No. 17 ~ No. 21 is so poor. In order to improve the hydrological condition, tidal flow mathematical model and physical model is set up to study flow field as while as wave physical model is set up to study waves. On the base of comprehensive comparison flow and waves factors, this paper analyzes the layout and hydraulic structures of Shatuozi diversion dike project, and explores the whole thought and research method of artificial measures to improve the hydrologic condition of port construction, which may serve as reference for other similar projects.
