摘要
公伯峡水电站拦河大坝为钢筋混凝土面板堆石坝,最大坝高132.2m,坝顶宽度10.0m,坝址处于较高地震区,河谷不对称,气候寒冷,日温差大,岩性变化复杂,开挖渣料质量差别大。在设计中充分考虑了这些特点,吸取国内外先进技术和经验,采用设置强透水区、混凝土挤压墙、左右岸高趾墙、坝体填筑全断面均衡上升、混凝土面板一次性连续施工等,保证了大坝设计的先进,加快了施工进度、保证了施工质量。
The retaining dam of Gongboxia Hydropower Station is a reinforced concrete face rockfill dam (CFRD) with a maximum height of 132.2m and a crest width of 10.0m. The dam site is located at higher seismic region where the canyon is asymmetric, and it is cold with the temperature changing dramatically, the rock property varies with complexity, and the excavated materials differ greatly in quality.These characteristics have been adequately considered in design, and the domestic and oversee advanced technology and experiences have been applied. These technology and experiences include: setting strong pervious zone, concrete extruding wall, high plinth wall at left and right banks; equalized rising of embankment fill in full section and once continuous construction for concrete face slab, etc. These methods guarantee the advanced design of the dam, speed up the construction progress and ensure the construction quality.
