| 摘 要： | 为了保证黄河河口水电站截流工程成功实施,进行了3个方案48个组次截流水工模型试验,获得了截流过程龙口的系列水流要素。模型试验表明:戗堤进占至龙口宽40 m以前,投抛的粒径为1~10 mm的石料未见流失;当龙口宽度减小到30 m以后,龙口流速及上下游水位差剧增,必须改用钢筋笼、混凝土四面体抛投以确保截流进占及龙口顺利合龙。

| Abstract: | In order to ensure the successful implementation of closure of the estuarial hydroelectric power plant of the Yellow River,it conducts hydraulic modeling of 48 groups(times) in 3 plans and obtains series key flow elements of closing point in the process of closure.The outcomes show that a) there is no loss of grain diameter of 1-10 mm of thrown rock material before the closing dike constructed to 40 m of closing point and;b) When the width of closing point reduces to 30 m,the velocity of closing point and t... |
