摘　　要：以拟建的缙云好溪名山桥为例,利用验证的船埠头大桥河流数学模型,对大桥建设后对河道防洪的影响和局部冲刷进行了技术分析,根据计算条件得到20年一遇洪水最大壅水高度为0.18m,壅水最大影响向上游在240m,对建桥引起的水位壅高和防洪能力降低,宜采取堤防加高加固方法,以满足防洪规划的要求.Taking the proposed Mingshan Bridge in Iinyun for example, the verified mathematics model of Wharf Bridge is used to analyze the influence of bridge construction on flood control. The value of river damming is estimated according to the calculation, with the maximum backwater height of 0.18 m and the biggest influence upstream of 240 m in 20 years. The strengthening methods to prevent flood, such as embankment heightening, are talked about in order to promote channel capacity to meet the requirements of flood control planning.
