The Valuation and Analysis to Flood Control for the four bridge in Guohe River

概述了涡河流域及涡河四桥的基本情况,涡河四桥建设后桥墩阻水会造成河道壅水及河道冲刷,通过分析计算分别得出河道壅水高度及河槽、河滩冲刷深度。依据计算结果,分析了大桥修建后对桥址处河段河势及河道防洪的影响,并提出了相应的防治补救措施。

This paper summarizes the basic situation of the Guohe River Basin and the four bridge in Gouhe River.The backwater and the river scour will be caused by the water resistance of the pier after the construction of the four bridge of the Guohe River.The backwater height of the river and the scour depth of the river channel and the river bank are obtained by the analysis and calculation.Based on the calculation results,the influences of bridge construction on river regime and river flood control at the bridge site are analyzed,and corresponding prevention and remedy measures are put forward.
