天然河道水面曲线计算的研讨

Study on the Calculation of Water Surface Profile along Natural River

目前在天然河道水面曲线计算中,流量模数的应用尚存在一些值得研讨的问题.从数学基本概念出发,结合水力学原理,对流量模数的计算提出了一些看法,认为按现行某些方式处理流量模数,将有可能导致所推算的水面曲线的水位偏高.以现有实例,按水面曲线图解方式,论证了合理选用流量模数计算的途径和方法,认为合理、可行.

： At present,the application of modulus of flow for the calculation of water surface profile along naturalriver， there are some problems,which are worthy to be considered． Some views are proposed on the calculation of modulus of flow based on the fundamental conception of mathematics combined with the principle of hydraulics．It is found the modulus of flow processed with certain ways will have the possibility to lead the water surface profile level on the high side at what point to be calculated．This method reasonably chosen to compute the modulus of flow based on the available examples and demonstrated by the way of water surface profile chart,which is believed reasonable and practical．
