【摘要】 分析了用Priessmann方法计算明渠—结合池—暗管结构的过渡过程的特点,给出了用明渠特征线方法算有压流的基本方程和建模过程。详细地分析了明渠—结合池—暗管结构在过渡过程计算中的边界条件。在编制程序对某具体的工程进行计算之后,指出了Priessmann法应用于明渠—结合池—暗管结构水力瞬变计算所应注意的问题,并对这些问题提出了相应的处理方法。更多还原

【Abstract】 The Priessmann method is applied to calculate the hydraulic transient of open channelsurge poolpressure conduit system. The basic equations for calculation of flow in pressure conduit by means of characteristic method are deduced and the numerical model for the system is established. Boundary conditions are analyzed. The problems occurred to the calculation are discussed according to the result of a typical open channelsurge poolpressure conduit system and the corresponding methods for solution are suggested.更多还原
