摘　　要：研制了不同规格的大型无粘性土渗透试验系统，包括试验装置、供水和测量系统。针对积石峡面板堆石坝的垫层料、过渡料等坝料进行了30余组试验，为大坝的设计施工提供了重要的依据。实际应用表明，该系统操作方便，测量精度高，可靠性好。Large-scale experiment systems of different sizes researching the penetrability of cohesionless soil have been developed, including the experiment equipment, the water-supply system and the measure system. Over 30 ex- periments in the cushion layer and transition layer material of JiShiXia CFRD were carried out, which provided important evidences for the design and construction of the dam. The practical application of the system showed that the system could be easily operated and gave precision measure results.
