弯曲河道内水深和流速平面分布的计算

Computation for Distribution of Depth and Velocity in Curved Open Channels

本文在分析弯道切向垂线平均流速和水面超高的基础上,建立了弯曲河道内水深和切向垂线平均流速平面分布的计算公式.该公式比以往仅能给出流速沿径向分布的计算公式更为优越.文中对有关公式进行了实验验证,成果表明,计算值与实测值基本一致.

Based on the analysis of both the tangential average velocity along vertical and the superelevation of the water surface in curved open channels, the formulas of computation for distribution of both the depth and the tangential average velocity along vertical in bends have been presented as following:The above formulas are better than those only tangential average velocity along vertical in radial direction, being given. By using exper imental data to verify these formulas, it is evident that the agree -ment between computation and measurement is satisfactory.
