摘要
水电站水工建筑物进水口形成的自由表面漏斗旋涡 ,对水利水电工程造成的危害性很大 ,进水口旋涡可通过合理设计、改善进口水流边界条件、修建专门的建筑物或安装专门的结构物予以消除 ;对于已建成的进水口 ,也可以通过合理的运行方式进行调整 ,在进行工程设计时 ,可根据进水口处地形特点 ,力求从经济合理、结构简单、便于施工、便于管理等方面进行权衡选取最佳防涡和消涡方案。文中的防涡。
A vertical vortex arised from intake of hydroulic structure does harm largely to water resources and hydro electrical project. Vortex can be suppressed by reliable design, improving the boundary condition, building and installing specific structure. For the finished intake, intake, it can be done by suitable operating way. When design engineering sturcture, that rational in economic, simple in structure and easy to control must be considered overall according to topographic features around the intake, in order to choose best scheme of vortex precaution and suppressing. The methods of vortex precaution and suppressing in the following can be studied and adopted in design by similar engineering structure.
