摘　　要：感潮河道水流属于非恒定流,其边界条件和初值条件较特殊,对于一维水力学模型可以采用解析方法求解。利用有限傅里叶变换理论,探讨了感潮河道一维水动力学的求解方法,并给出了计算公式和算例。The tided river flow is belog to unsteady flow. Its boundary conditions and initialized conditions are special. Analytic method is able to solve one-dimensional hydraulic model. The Calculation problem of tided stream hydrodynamics is discussed in this article. Finite Fourer transformation is applied to calculation of tided stream hydrodynamics. The calculation equations and numerical example are given.
