At first, this paper analyzes the factors of water - sand influencing water level of yellow river and the feasibility just using the factors of water - sand to study water level, and collects the corresponding data ; secondly, because there are strong nonlinear relation in the corresponding data, by meticulous theory analysis, this paper integrates basic nonlinear analysis method, theory of random analysis, method of least squares and so on. it puts forward a method which can get the high accuracy simulation of the data, perfects the multi - factor analysis of variable ( over three factors ) of the statistic ; thirdly, it applies the method to the approximation of corresponding water level process which belong to the capacity of sand of middle - high and middle - low, and get the high - accuracy simulation about the typical nonlinear relation ; at last, this paper definitudes the main influence mode that the capacity of sand. it mainly unite with other factors to work on the water level in the yellow river lower reaches ; mor eover, this paper analyzes the difficult point and the direction of improvement to realize the accuracy forecasting of the flood level of erodible - bed channel
首先，系統分析了影響黃河水位的水沙因素，及僅用水沙因素有效研究水位的可行性，並按變量對應思想採集它們的相應數據；其次，由於相應水位過程數據中含極強的非線性關系，本論文經細致的理論分析，將基本的非線性分析方法、統計建模方法、隨機分析理論、最小均方誤差原則等等數學理論及方法有機揉合，提出了能有效實現這類數據高精度擬合的分層篩選法，並改進了統計學中多因子（三個以上）方差分析法；再次，將這一方法用於黃河中高及中低含沙類洪水相應水位過程的擬合，實現了這一典型非線性關系的高精度擬合，各年汛期上下游相應洪水位過程的擬合誤差都較小；最後，明確黃河下游含沙量對水位的主要影響方式，即含沙量主要是與其它因素聯合對水位作用；另外分析了要實現變動河床洪水位過程準確預報的困難所在及改進方向。By hydraulic modeling, this paper describes studies on the stability of a floating bulkhead operating in standing water and flowing water, and it ' s hydrodynamic stability characteristics that distinguish in standing water from in flowing water ; and direct measurements of the forces acting on the model floating body during floating and sinking is taken. as a result, the rotation stress curves are produced and analyzed ; to provide data for optimum operation schedule analyses of the sluice, the relationship of the impact forces acting on the side wall of the gate and the running speed is studied ; the reasons of unstably uplifting of the bulkhead are discussed and the method to solve the problem is also given in this paper
本文結合常州新閘防洪控制工程水工模型試驗，系統分析了浮箱門在靜水和動水中的穩定性及其影響因素，指出靜水穩性和動水穩性的不同特點；試驗測定了浮箱門動水運行時的受力情況，給出並分析了定位過程轉動力的變化過程曲線；根據浮箱門啟閉速度與門體和岸墻之間撞擊力大小的關系，選擇合理的動力設備，為設計和工程實踐提供可靠依據；分析浮箱門難以穩定上浮的原因，並給出解決方案。( 2 ) a series of experiments on time scale distortion are made with real river model, inflow and outflow boundary condition, and continuous simulation. by means of analysis of the experimental data on model water level, water - surface gradient, cross velocity, outflow discharge process and the sediment transportation capacity, the main physical reasons for the above hydraulic parameters deviations caused by time scale distortion are illustrated : response delay of model channel storage capacity and rate of water level with time
（ 2 ）採用真實的河工模型和入出流邊界控制條件以及連續模擬的方法進行了有關時間變態率的系列試驗，通過模型水位、比降、流速、出口流量過程線和斷面挾沙力試驗資料的分析，闡明了時間變態引起上述各種水力參數偏離的主要物理原因：模型的槽蓄響應和洪水過程時間變化率的響應滯后。By use of many years ' hydrologic data, the max, water quantity dated from every day may be counted in every year ' s flood season, and the designed water quantity corresponds to the definite frequency
滑動汛期水位在多年資料基礎上，通過統計汛期中每日為起點的最大來水量，求出固定頻率的設計來水量，選擇合適的典型洪水過程線進行調洪計算后得到每天的汛限水位。分享友人
