利用三维模型计算所得结果,建立了重庆(九龙坡~铜锣峡)河段沿程水位与上游流量、三峡坝前水位关系的公式。验证表明,公式可在一定条件下较准确反映不同流量下坝前水位对于重庆河段水位的影响。利用公式,可根据上游流量做出快速响应,为重庆河段的防洪和通航提供参考。
A formula for predicting water level in the Chongqing reach is established through a symmetrical analysis on the simulation data of a 3D numerical model. Verification shows that this formula can accurately reflect the relationship between the Chongqing water level and the dam operating water level. The formula can be used to predict the water level responses to different upstream flow rates and the water levels at the Three Gorge dam, and it also lends a reference for operation of the Three Gorge reservior.
