摘要: 在收集大量水文资料的基础上,采用数值分析的方法,得到三峡成库初期对长江寸滩站水位流量关系产生影响的临界坝前水位为156 m。以此临界水位为界,在坝前水位之下重庆主城河段处于天然状态,之上则为库区或回水变动区状态。同时给出了三峡成库初期寸滩水文站的水位流量关系曲线,采用分流量级拟合的方法,可获得较好的结果。

Abstract: On the basis of collecting a large number of hydrological data, using the method of numerical analysis, it showed that critical water level which impacted on Cuntan station in Chongqing reach water-flow relationship after the Three Gorges Reservoir was 156 m. This critical water level was taken as a bound. When the water level was below it, Chongqing reach was in natural state; when the water level was above it, Chongqing reach was the reservoir or the fluctuating back water district. The water flow curve of Cuntan station in the early years of the Three Gorges Reservoir was available. The result shows water-flow relationship adopting the method of shunt magnitude in the fluctuating back water district is good.

Key words: hydraulic engineering, Three Gorges Reservoir, critical level, water-flow relationship
