近年来,我市几项中小型骨干水库的陡坡溢洪道工程,经过了水工模型试验的验证和修改,采用了平台扩散段的型式,经济和消能效果颇为显著.这些平台扩散水跃消能工,其组成有陡坡段、平台(或反坡)扩散段和消力池,其中扩散段与消力池的纵向衔接采用曲线(渥奇曲线).其特点是使从陡坡段流来的急速而且集中的水流,经过平台段时按一定的合适角度扩散,急流水面渐渐加宽从而减小单宽流量,然后进入消力池借
In recent years, the steep slope spillway project of several small and medium-sized backbone reservoirs in our city has been verified and modified by the hydraulic model test and has adopted the type of platform diffusion section, and the economic and energy dissipation effects are remarkable. It can be composed of steep slope section, platform (or reverse slope) diffusion section and stilling basin, in which the longitudinal convergence of the diffusion section and the stilling basin adopts a curve (woth curve), which is characterized by flowing from the steep section The rapid and concentrated flow of water spreads through the platform section at a certain suitable angle, and the surface water of the rapids is gradually widened to reduce the flow rate of single width and then enter the stilling pool
