摘要
采穴河上修建桥梁必然会对河道水位和流态产生影响,为了分析南河大桥对采穴河的防洪影响情况,建立了正交曲线坐标下平面二维水流数学模型,并应用该模型对采穴河修建南河大桥前后的水流情况进行了模拟预测。模型计算结果表明,桥梁修建后对工程附近河段水位和流速影响均较小,基本上不会对采穴河防洪产生不利影响。
Constructing a bridge on the river surely may affect runway water level and stream state ,It＇s built two dimensional orthoganality curve coordinate streams mathematic model for analysis south River bridge build affect to the CaiXue river flood control, apply the mathematic model to simulate and forecast the streams of the South River bridge building front and back . The model calculate result indicates that there is little affection to the channel segment water level and flow rate effect , are unable to affect the flood control to Caixue river.
