行洪河道整治工程模型设计与试验研究

Model Design and Test of River Training for Flood Discharge River

针对沂河整治工程初设方案和第 2设计方案 ,对沂河开挖中泓后行洪及泥沙淤积情况进行河道模型试验 ,研究河道行洪水流特性和泥沙淤积规律及其影响因素以及因白马河出口上移引起的水流变化及泥沙淤积变化。

Based on the first and second designs for Yihe river reconstruction, a model test is carried out to study flow characteristics, sediment aggregation and its affect factors after the center ditch in the river is deigned and built. The changes of flow characteristics and sediment aggregation caused by the movement of Baima river mouth are also studied. The research results may form reliable basis for design and reconstruction of flood discharge river.
