摘要: 选取石鼓水文站2014年~2017年收集的水文资料进行整理，对多次典型洪水过程不同涨落率条件下的水位流量关系对比分析可知，石鼓水文站中高水时受下游弯道顶托水位流量关系呈逆时针绳套，且涨落率越大，断面上的流量与同水位稳定的流量相比越大，水位涨落急剧时，洪峰绳套线型越矮胖，幅度越宽，反之，绳套越尖瘦，幅度越狭窄；在一定水位级下，洪水涨落比较缓慢时将不出现绳套。
Abstract: Based on the observed flood data from 2014 to 2017 at the Shigu hydrological station, the water level discharge relationship under different flood fluctuation rates of several typical flood processes is analyzed. The middle and high water level is supported by the water level of the lower bend, the relationship between the water level and flow rate becomes counterclockwise loop curve. The larger the fluctuation rate is, the greater the flow rate and the wider the amplitude are in the cross section by comparison with the stable water level. On the contrary, the thinner the loop curve, the narrower the amplitude is; at a certain water level, the flood fluctuation is relatively slow and the loop curve will disappear gradually.
