【摘要】 从工程实际出发,提出了特殊的渠道断面———悬链线断面。根据数学分析和水力学原理,给出了在悬链线形横断面尺寸、纵坡、糙率等已定条件下其正常水深求解的迅速收敛迭代公式。同时,水力公式求解精度高,迭代次数少,避免了传统算法反复试算的弊端,在工程设计上具有参考价值。更多还原

【Abstract】 This paper put foreword special canal section catenary’s suspension alignment section from engineering practices.According to mathematical analysis and hydraulics principles,the author gives rapid convergent iteration formula of normal water depth solution at already settled condition of catenary’s suspension alignment section size.longitudinal grade,roughness coefficient and so on.At some time,the precision of hydraulic formula solution is high,the iteration times are less.It avoided the shortcoming of traditional calculation,namely repeatedly calculating,and has reference value at engineering design.更多还原
