利用斜槛消减弯道急流冲击波的应用

泄水建筑物在陡槽段由于地形、地质条件等因素限制常设置有弯道,这种情况下,当水流通过时不可避免将产生急流冲击波,对工程安全运行极其不利,为此,实际工程须采取相应措施对之加以处理。本文围绕克纳普所提的斜槛法,结合桑株河水库、平定河水库、凤凰水库等工程实践,对斜槛设计及布置进行了归纳总结。实践成果表明:斜槛法的合理应用对消减弯道急流冲击波能起到显著效果。

The Application of Slopping Sills to Eliminate Supercritical Flow Shock Wave in Curved Channel

Due to the restriction of some factors such as topographic and geological conditions,curved channel was normally set up in the chute of discharge structure.In this way,a series of supercritical flow shock waves were produced when water flow passed the curved channel in the chute.Under this condition,the normal functions of engineering would suffered from disadvantageous influence.Therefore,adopting some measures to deal with that problem in actual project is necessary.Through introducing the basic theory of...
