摘　　要：砾石土料作为300 m级超高堆石坝的心墙材料,其质量控制标准一直施工过程中的技术难题。瀑布沟、糯扎渡、长河坝、两河口等水电工程施工经验及研究成果表明,现有的碾压设备可满足300 m级超高砾石土心墙堆石坝的建设需要。根据砾石土特点、碾压设备性能和超高坝质量要求,提出砾石土料的质量控制标准,为在建和拟建的超高堆石坝砾石土料的质量控制提供依据。When taking gravel soil as core wall material of 300 m-level high rockfill dam, the quality control standard of gravel soil material always is a technical problem in construction process. The experiences and research results of the construction of hydropower projects such as Pubugou, Nuozhadu, Changheba and Lianghekou show that the existing rolling equipment can meet the construction needs of 300 m-level high gravel soil core wall rockfill dam. According to the characteristics of gravel soil, the performance of rolling compaction equipment and the quality requirements of ultra-high dam, the quality control standard of gravel soil is put forward to provide a basis for the quality control of gravelly soil materials in existing high rockfill dam under construction or under planned.
