摘要
基于圆形过水断面的几何特点与棱柱体水平明渠的水跃方程,推导出圆形断面的水跃方程。通过数学变换,得到了圆形断面水跃共轭水深计算公式。针对具体算例,采用图解法与迭代计算相结合的办法对圆形断面的共轭水深进行了求解。算例表明,该计算方法简单、结果精确,便于推广应用。
Based on the geometric features of circular cross-section and the hydraulic jump equation of general prismatic channels, the hydraulic jump equation of channels with circular cross-section was deduced. Then through appropriate mathematical transformation, the calculation formula of conjugate depth for circular chan- nels was developed, and the graphic method and the iterative method were used together to obtain the conju- gate depth. The example showed that the method was simple, reliable, accurate and convenient in practical en- gineering application.
