某小型水电站首部枢纽底格栏栅坝尺寸的确定

The determination of the mesh fence dam dimension in the head of Small-sized Hydroelectric Power Station

底格栏栅坝在我国应用较广,适用于河床坡度较陡,水流中带有大量的卵石、砾石及粗沙的山溪河道上,它可以防止大量泥沙进入渠道,而且具有结构简单、施工方便及造价低廉等优点,本文对该水电站及首部枢纽作了简要介绍,同时确定了底格栏栅坝的相关尺寸。

The mesh fence dam is used widely in China for steep river bed, with a large number of pebbles in water, gravel and coarse river in mountain streams, it not only can prevent a large number of sediment into the channel, but also has advantages of simple structure, easy construction and low cost.
