莲花水电站是我国在寒冷地区建设的一座大型水电站，枢纽由面板堆石坝、砂砾石二坝、岸坡式溢洪道和引水发电系统组成。施工过程中，采用大型钢模台车、滑升模板、扇形孔爆破等较先进的施工技术和工艺，加快了施工进度，大坝混凝土面板施工质量优良、裂缝数量少，蓄水后，经观测资料分析显示，大坝渗流量较小，坝体最大垂直沉降仅为１３．３９ｃｍ。实践证明，先进施工工艺和技术是确保工程质量和进度的重要手段 The Lianhua Hydropower Station is a large hydropower station constructed in the cold area in China. The hydropower station is composed of the face rockfill dam, sand and gravel dam, bank spillway and diversion system. In the process of construction, more advanced construction techniques and processes such as large-scale steel mold trolley, sliding formwork and fan-shaped hole blasting are adopted to speed up the construction progress. The dam concrete slab construction quality is good, the number of cracks is small, and after water storage, Data analysis shows that the dam seepage flow is small, the maximum vertical settlement of the dam is only 13.39cm. Practice has proved that advanced construction technology and technology is an important means to ensure project quality and progress
