【摘要】 掺气分流墩是首次应用于柘林水电站的一种新型掺气消能减蚀(防冲)设施。通过原型观测试验研究和超过正常水位的运用检验表明:掺气分流墩掺气减蚀效果显著。本文介绍了这次原型观测的主要成果,对其特殊的局部水力现象,水流脉动和墩体振动特性,水流掺气雾化,以及掺气消能减蚀效果等进行了探讨。更多还原

【Abstract】 The aerated flow splitting pier firstly applied in Zhalin Hydropower Station, is a new type facility for dissipation of energy, mitigating cavita-tion damage and erosion.Through experimental research and prototype observation notable results of decreasing erosion has been obtained by vising aeratedflow splitting pier, and the stability of the pier is also safe and reliable.In the paper, the principal result of the prototype observation is presented, and the special local hydraulic phenomenon, flow pulsation, vibration character of the pier, aerated fogging, dissipation of energy and effect of decreasing erosion are also discussed.更多还原
