【摘要】：流量影响线法是一种基于历史洪水水痕的设计流量计算方法,因外业资料收集工作量小、计算简便,在桥梁水文计算中得到应用。本文使用单参数分析方法对流量影响线各参数做出了计算分析,得出了"标定洪水高程"的测量误差应控制在5%以内,其它参数的测量误差可以控制在10%以内的结论,可供桥涵水文勘测参考。
[Abstract]:The flow influence line method is a design flow calculation method based on the historical flood water mark. Because the collection of external data is small and the calculation is simple, it is applied in the hydrological calculation of the bridge. This paper uses the single parameter analysis method to calculate and analyze the parameters of the flow influence line, and concludes that the measurement error of the "calibrated Flood Elevation" should be controlled. Within 5%, the measurement error of other parameters can be controlled within 10%, which can be used for reference in hydrologic investigation of bridges and culverts.
