摘　　要：采用自主研发的粗粒料大型高压渗透仪对积石峡水电站混凝土面板堆石坝坝料进行试验研究,确定了垫层料、过渡料的渗透系数,垫层料与过渡料层间的过渡关系及在试验条件下垫层料、过渡料不发生破坏的渗透比降极限。The self-developed coarse-grained high-pressure permeameter is used to test the permeability of dam materials for Jishixia CFRD. The permeability coefficients of cushion material and transition material are determined. The permeability gradient relation between cushion material and transition material layers is also defined and the gradient limits in which tile cushion material and transition material do not have damage are also determined under the experimental conditions.
