跌扩型底流消能工压力分布特性的试验研究
Experimental Study on Characteristic of Pressure Distribution about the Falling-sill and Expanding Bottom-flow Energy Dissipater
摘要
Abstract
Based on the method of hydraulic test the influence of expansion ratio, depth of the falling-sill and the flowing-in Froude number on the hydro-dynamic pressure in impact area of the stilling basin bottom is analyzed emphatically.The research results show choosing the appropriate expansion ratio,depth of the falling sill and the flowing in Froude number can lower the hydraulics indicators of the stilling basin bottom and the sidewall effectively in the falling-sill and expanding bottom-flow energy dissipater.Under the optimum combination they can not only keep the energy dissipate ratio higher but also can keep the hydro-dynamic pressure lower to avert the bottom plates from levee slipping in impact area of the stilling basin bottom and the sidewall.关键词
