| 摘 要： | 河势演变和水流的动力学特性,对水利工程安全和穿越管道的防护设计具有重要意义。本文结合不同洪水流量时的河势演变,给出了不同水流的水面差值,横向垂线流速分布,环流的环量和环流间的诱导速度;分析了水流及其动力学特性产生的横向与纵向作用力,动量和动量矩的作用,可能出现的绕流升力和压差阻力等,为类似研究与工程设计提供一个范例。

| Abstract: | River regime and hydrodynamic characteristics have great significance to both the hydraulic engineering security and designing the pipeline across the river avoiding damage.Combining with the river regime at different flood discharge,this article presented the difference of water leves with different flow,the lateral distribution of vertical velocity in cross section,the circulation and the induced velocity.This paper analyzed the dynamics of the flow that induces longitudinal force and lateral force,influence of momentum and angular momentum,lift force of ambient flow and pressure drag that may emerge,etc.It also provides an exemplification for similar research and design. |
