公伯峡水电站的拦河大坝为钢筋混凝土面板堆石坝 ,最大坝高 139 0m。该坝的特点是 :坝址处于高地震区且河谷极不对称 ,气候寒冷 ,日温差大、干燥 ,岩性变化复杂 ,开挖渣料质量差别大 ,两岸上游设有目前国内较高的混凝土高趾墙。在设计中充分考虑了这些特点 ,就坝体稳定、应力应变分析、坝体分区、坝料平衡、接缝止水结构设计、混凝土高趾墙等进行了深入研究和优化设计
The dam of Gongboxia Hydropower Station is a reinforced concrete face rockfill dam with a maximum dam height of 139 0m. The dam is characterized by: the dam site is in a high seismic zone and the river valley is extremely asymmetrical; the climate is cold; the daily temperature difference is large; the dryness and the lithology change are complicated; the quality of the excavated slag is quite different; and there are currently relatively high concrete High toe wall. In the design, these characteristics are fully taken into consideration, and in-depth research and optimization design are carried out on the stability of dam, stress and strain analysis, dam partition, dam material balance, design of sewer sealing structure and concrete high toe wall
