摘要
金沙江大雪滩群是控制水富至宜宾航道等级提高的关键控制滩段,紧邻金沙江与岷江汇合口,水位流量关系十分复杂。通过众多实测资料的详细统计分析,提出了金沙江汇流比频率曲线,统计了最可能出现的汇流比,建议用于滩段研究宜选用的汇流比,并给出了单一的滩段控制水尺与两江流量的关系,可为该滩段航道整治等工程的设计和研究提供参考。
The Daxuetan shoals in Jingsha River is the key controlling river reach for increasing the discharge capacity of waterway from Shuifu to Yinbin.It is adjacent to the confluence of Jinsha River and Min River and the relationship of stage and discharge is very complicated.Based on the real-measured data,this paper gives the frequency curve of afflux ratio and the frequency afflux ratio most possibly occur and proposes the suggestion to the afflux ration to be used for the research.The simple relationship of stage and total discharge is also presented.The result may serve as reference for the waterway regulation engineering in this river reach.
