绘制天然河道水面曲线的图解计算法
GRAPHIC CALCULATION METHOD IN DRAWING THE FLOW PROFILE IN THE NATURAL CHANNEL
【摘要】 本文根据流量模数的倒数曲线法,利用合轴图及数值叠加规则,提出了一种适用于山区河道的图解计算方法,本法解算过程较为直观,便于检查正误,计算精度较高,特别是在需要绘制一系列流量水面曲线的情况下,可加快计算的进度。
【Abstract】 Based on the reciprocal curvilinear approach of discharge modulus, with the application of the coaxial diagram and the numerical superposition rule, a graphic calculation applicable to rivers in the mountainous areas is put forward. The method is comparatively direct with a high accuracy and an easiness to check the errors. It can accelerate the operational speed when a series of flow profiles are required.
