摘　　要：建立大辽河口二维潮流数学模型,分别对工程建设前后潮流场进行模拟计算。计算结果显示,由于舾装码头及引堤工程缩窄了盖州滩东侧至双台子河口的主流通道,使得周围海区的水动力环境发生了一定变化,受工程影响工程区西侧(双台子河口一侧)流速增大,工程区东侧(大辽河口一侧)西水道入口处流速受围填二期影响略有减弱,东水道基本不受工程影响。Based on establishing two- dimensional mathematical model of tidal current at Daliaohe Estuary, tidal current field before and after construction was simulated and analyzed. The results show that the mainstream channel form east side of Gaizhou Beach to Shuangtaizi Estuary is narrowed by outfitting quay and seawall projects, then the hydrodynamic environment is changed around the coastal seas. Influenced by the project, velocity of flow at the west side （nearby Shuangtaizi Estuary） is increased, while the velocity at west course entry of the east side （nearby Daliaohe Estuary） is decreased after reclamation. East course is not influenced by the project.
