摘　　要：根据三维数学模型计算所得的不同坝前水位和上游流量下的重庆主城区水位公式,建立三峡水库坝前水位对于重庆主城区(九龙坡—铜锣峡)河段的壅水高度公式,公式可综合反映重庆主城区壅水高度与坝前水位关系,根据公式给出考虑重庆主城区防洪的坝前最高水位和最佳水位,可为三峡水库坝前水位调度提供参考。An understanding of the optimum pre-dam water level of the Three Gorges Reservoir corresponding to flood control of the varying backwater zone is significant to reservoir regulation. Based on the water level formula obtained from a three-dimensional mathematical model with different pre-dam water levels and upstream discharges, a swell height formula for the pre-dam water level of the Three Gorges Reservoir relative to the reach of the main urban area of Chongqing ( Jiulongpo to Tongluoxia) was built. The swell height formula can comprehensively reflect the relationship between the swell height of the main urban area of Chongqing and the pre-dam water level. The swell height formula also provides the maximum pre-dam water level and optimum pre-dam water level considering flood control of the main urban area of Chongqing, which can serve as a reference for pre-dam water level regulation of the Three Gorges Reservoir.
