一、前言在参考文献(1)和(2)中,作者曾对侧槽式溢洪道单纯就其平均水面线的计算进行了分析研究,而对水工布置设计中的问题,则未曾涉及。在这方面,值得提出探讨的是有关侧槽式溢洪道的泄流平稳和设计经济合理方面的问题。通常侧槽式溢洪道的水力计算只是计算横断面上的平均水面线,这对于总体布置设计当然是十分重要的,但它不能反映水流的全部情 I. INTRODUCTION In references (1) and (2), the author has conducted an analysis of the calculation of the average surface water line of the side channel spillway, but has not dealt with the problems in the design of the hydraulic layout. In this regard, it is worth discussing the issues concerning the smooth discharge of side-channel spillways and their economically sound design. Often the hydrodynamic calculation of the side channel spillway is only the calculation of the average waterline in the cross section, which of course is very important for the overall layout design, but it does not reflect the full extent of the water flow
