芭蕉河二级水电站浆砌石拱坝设计

Design for Masonry Arch Dam of Bajiao River-Ⅱ Hydropower Station

芭蕉河二级水电站挡水建筑物为浆砌石双曲拱坝,采用浆砌石坝体自身防渗的防渗形式。泄水建筑物为坝顶泄洪表孔和坝身泄洪中孔,分别采用大差动齿坎和窄缝挑流消能工。模型试验和实际运行表明,浆砌石拱坝体型、坝体防渗及泄水建筑物等设计是成功的。

The outline of the masonry arch dam is double-curved, the dam body is impervious, the crest spillway is built of slotted-type bucket and the mid-discharge orifice is slit-type bucket. The data of model test and proto observation show that the design of the dam is successful.
