摘要
九甸峡水利枢纽工程混凝土面板堆石坝建在深厚覆盖层上,坝址处为不对称狭窄河谷,岸坡陡峭。在高陡岸坡处理、深厚覆盖层基础处理、高地震区抗震措施以及高寒、高海拔地区堆石坝施工技术等专题研究的基础上,对混凝土面板堆石坝、坝基开挖及基础处理以及坝基深覆盖层处理进行了设计,并对坝体稳定性及应力应变进行了分析。计算和观测数据分析表明,其成果满足规范要求,为深厚覆盖层及不对称狭窄河谷上建造高面板堆石坝的一次成功探索。
The CFRD dam of Jiudianxia Water Project founds on deep overburden and the dam site locates on asymmetric narrow valley with steep slopes.After adopting the study results on slope treatment,deep overburden treatment,earthquake-resistance measure and CFRD dam construction technology in high-cold and high-altitude area,the CFRD dam,the dam foundation excavation and treatment and the deep overburden treatment were designed.The dam stability and the stress and strain were also numerically analyzed.The simulation and monitoring data analysis shows that the design meets the requirements of specifications and is a successful practices for constructing high CFRD dam on deep overburden and asymmetric narrow valley.
