通过物理模型试验分析军庄—三家店河段的水流、泥沙运动,研究河床演变规律。定床试验给出了分汊河道的分流比及分流点,不同频率洪水的水位、流速、流态、流势。动床试验分析遭遇20年、50年洪水河道的冲淤演变规律,为该河段的河道整治提出相应的建议。
Through the physical model test, the water flow and sediment movement in the Junzhuang-Sanjiandi reach were studied to study the evolution of the riverbed. The fixed bed test shows the diversion ratio, diversion points and water levels, flow velocities, flow regimes and flows of floods at different frequencies. The dynamic bed experiment analyzes the law of erosion and silting evolved after 20 years and 50 years of flooding, and puts forward corresponding suggestions for the river regulation of this section.
