摘要
寻求合适的渗控措施以解决坝的渗流问题是高碾压混凝土坝技术发展的关键。以光照水电站200米级RCC重力坝为依托,利用节点虚流量全域迭代法和改进的排水孔模拟技术,对该坝上游面拟采用变态混凝土与二级配碾压混凝上组合防渗结构方案防渗效果进行了分析;研究了坝体可能出现的裂缝和排水孔幕的渗控作用。研究表明:该防渗型式可行,优势明显,能满足200米级RCC重力坝渗控要求,综合分析后提出了优选方案。
It is key of development high RCC dam to find the seepage control measure to solve seepage.Based on the structural design of about 200m RCC gravity dam of Guangzhao Hydropower project,the effectiveness of the seepage control schemes of the combination of distorted concrete face slab on dam up stream side with two graded aggregate RCC was analyzed by using procedure of nodal virtual flux of global iteration and improved method of drainage hole in detail;Mean while,the seepage control effect of drainage curta...
