分析結果表明,調水調沙不僅能夠減少河道淤積,而且能夠有效增大主槽的過流能力,改善下遊河道排沙條件。Since boundary of the lower yellow river bed varies with the flow conditions, main channel of the stream continually shrank and flood control becomes rather difficult
隨著黃河下游水沙條件的不斷變化,河道的邊界條件也隨之發生變化,主槽嚴重萎縮,泄洪能力日臻下降,防洪問題日益突出。First the author memorized the yellow river excavation history and concluded development of modern dredging science, and found that most researches of dredging are related to navigation regulation, little used to flood control especially in the yellow river with silty. based on the experiment of generalized physical model of the lower reach of the yellow river, and the study of the loaden flow mechanism and the dredging efficiency, the author get some new ideas as follows : 1
通過對黃河疏浚的歷史以及現代疏浚工程學的發展進行了回顧和總結,認為已有的疏浚研究大多基於航道疏浚工程,對于防洪疏浚特別是在黃河這種多沙型河流上進行防洪疏浚的研究極為欠缺,本文基於黃河下遊河道概化模型試驗,對疏浚挖槽后水沙運動機理及效果等進行了研究,得到以下認識。An experimental research on notching wet beach of the yellow river with the short - delay blasting is made for eliminating the risk that the main river channel is often threatened by some horizontal and slanting streams occurred on the downstream of the river and solving the problems from the bend cut - off for river channel harnessing, water way dredging and the siltation of the water diversion outlets along the channel

概括總結出了河段疏浚挖槽后,疏浚挖槽河段及其上下影響河段的河床演變及水面線變化的模式,即挖槽段逐漸回淤,挖槽上游段逐漸沖刷,並且其回淤及沖刷的強度隨時間的推移由大變小。( 2 ) the key problem to the application of muskingum approach, in another word, there exists non - linear effect. therefore, to meet the demand of practical engineering to a more satisfactory extent, it is vital to convert the linear formula in muskingum model to a non - linear one
2 、在水文學中馬斯京根( muskingum )法是河道洪水演算中廣泛應用的方法,因該槽蓄方程是線性的,即把k , x在一定河段內假定為常數,這在某些情況下是不切實際的,為此必須將馬斯京根模型中線性的槽蓄方程非線性化,才能更好地滿足實際工程的需要。Abstract : variations of flow pattern, flow velocity in deep poo l and side bar, mainstream thread, and water surface, caused by excavation project, are investigated by two - dimensional mathematical model in an orthogonal curvili near coordinate system. the change of bed - load transport rate, and redeposition r ate are predicted. the influences of the excavation project on navigation are ana lyzed. grid - type and flat - type excavation alternatives are proposed and discuss ed
