摘　　要：溢洪道是混凝土坝宣泄洪水的重要泄水建筑物,必须保证施工质量才能有效实现泄水功能、保证大坝稳定。溢洪道由于其所在部位及功能的特殊性,高差大、坡度陡且底板进出口线形复杂,施工难度大,在溢洪道施工中,采用普通平面钢模板随混凝土浇筑上升而翻升、拆模后对底板面收面压光的方法可保证溢洪道底板按设计成型,且能保证混凝土浇筑质量。Spillway is an important discharge structure for concrete dam to release flood.Only by ensuring the construction quality can the discharge function be effectively realized and the dam stability can be guaranteed.Due to the particularity of its location and function,the spillway has large height difference,steep slope and complex shape of floor inlet and outlet,which makes the construction difficult.In the construction of spillway,the common plane steel formwork is turned up along with the concrete pouring,and the bottom plate surface is finished and polished after the formwork is removed,which can ensure the spillway bottom plate to be shaped according to the design and ensure the quality of concrete pouring.
