水位流量单值化新方法—稳定流量通式法

New Single-valued Processing of Stage-Discharge Relationship:General Steady Discharge Formula

从马斯京根槽蓄曲线方程入手并结合校正因数法,通过合理假定及数学演算,提出一种新的水位流量单值化方法——稳定流量通式法,将绳套形的水位~流量关系曲线经此方法较快地计算出稳定的水位~流量关系曲线,不需另设参证水尺,借助由实测资料制作的工作曲线就可进行计算。对于河床较稳定、主要受洪水涨落率影响且大小绳套的轴线基本重合的测站,该方法会获得满意的成果。

Based on the Muskingum channel storage curve equation and correction factor,this paper presented a new method of establishing single-valued stage-discharge relationship through rational assumption and mathematical calculation,which is the general steady discharge formula.The main advantage of this method is the steady stage-discharge relationship curve that can be derived quickly from the loop curve of stage-discharge relationship without reference water gauge.It can facilitate the single-valued processing with satisfied results for those flood-effected gauging stations with stable river bed and basically superposed axis of large and small loops.
