通过平面弧形双开闸门物理模型试验，对闸门对称开启、不对称开启和浮起运行三种情况的闸下水流流态进行了观测，测量闸门上下游水位、过闸流量、闸门开度等水力参数，分析闸下水流流态，总结出平面弧形双开闸门运行时闸下水流流动的特性。闸门对称开启时，闸下没有影响闸门运行的不良流态，主流居中，两侧回流区对称；闸门不对称开启时，闸门的开度小比开度大时对流态的影响大；闸门浮起运行时，闸下海漫段主流偏于两侧，河道中心部位形成两个强弱周期转换的回流区。
通過平麵弧形雙開閘門物理模型試驗，對閘門對稱開啟、不對稱開啟和浮起運行三種情況的閘下水流流態進行瞭觀測，測量閘門上下遊水位、過閘流量、閘門開度等水力參數，分析閘下水流流態，總結齣平麵弧形雙開閘門運行時閘下水流流動的特性。閘門對稱開啟時，閘下沒有影響閘門運行的不良流態，主流居中，兩側迴流區對稱；閘門不對稱開啟時，閘門的開度小比開度大時對流態的影響大；閘門浮起運行時，閘下海漫段主流偏于兩側，河道中心部位形成兩箇彊弱週期轉換的迴流區。

It had been tested by the physical model test on the plane segment double gate,according to observing the three cases of the symmetrical open double gate,the asymmetrical open double gate and the floating gate operation,measuring the hydraulic parameters such as upstream and downstream water level of the gate,water discharge through sluice and the gate opening and analyzing the flow pattern after the current of double gate,it can summarize the flow characteristics when the plane segment double gate is working. When opening the gate symmetry,there have no ad-verse effects of flow pattern under sluice gate operation,the mainstream in concentrated in the middle of the river,and the recirculation zone is sym-metry on both sides of the gate. When opening the gate asymmetry,the smaller gate opening has great influence of the flow pattern than the bigger gate opening. When the floating gate operation,the mainstream is concentrated in the both sides of the sea overflow section,the river formed at the central part of two weak period conversion of the recirculation zone.
