摘　　要：水利水电工程大坝面板结构主要采用钢筋混凝土材料,为加快抽水蓄能电站大坝面板混凝土的施工进度和降低施工成本,基于玻璃纤维筋质量轻、抗拉强度高、材料结合力强和耐腐蚀性强等特性,研究在其大坝面板中混合采用“玻璃纤维筋+钢筋”的施工应用。经过下水库面板混凝土采用玻璃纤维筋的试验以及上水库面板大规模混合使用“玻璃纤维筋+钢筋”,通过和传统钢筋混凝土面板对比,发现混合使用“玻璃纤维筋+钢筋”方案能够加快施工进度和降低施工成本。The face slab of dam structure of water conservancy and hydropower projects mostly adopts reinforced concrete materials.In order to accelerate the construction progress and reduce the construction cost of face slab concrete of the dam of pumped storage power station,this paper studies the combined construction application of glass fiber bar and steel bar in the face slab of dam basing on the glass fiber bar’s characteristics of light weight,high tensile strength,strong material adhesion and strong corrosion resistance.After the reinforcement test of adopting glass fiber bar in the face slab concrete of the lower reservoir,large-scale combined application of glass fiber bar and steel bar has been conducted in the face slab of the upper reservoir.Comparison with the traditional reinforced concrete face slab shows that combined application of glass fiber bar and steel bar can accelerate the construction progress and reduce the construction cost.
