摘　　要：针对反弧段急变流收缩断面水深的计算问题,基于其动水压力分布规律,分析了考虑离心力作用项与常规计算所得的收缩断面水深的差异,并采用牛顿迭代法推导出考虑离心力作用项的收缩断面水深的迭代计算公式。同时,由水工模型试验验证了计算结果的合理性和准确性。For the calculation of water depth of rapidly varied flow of contraction section in deflector bucket, considering the centrifugal force action item, the new calculation formula of water depth is deduced by using Newton iteration method based on dynamic water pressure distribution rule. And then the differences between the traditional method and new method are discussed. Meanwhile, the rationality and correctness of the calculation result has been verified by hydraulic model experiment.
