摘　　要：纳子峡水电站工程大坝坝型为混凝土面板砂砾石坝,目前大坝填筑已完工。施工过程中建立和实施了有效的质量监督机制,主坝砂砾料通过覆盖层开挖、采料、卸料、摊铺、洒水、碾压、干密度测定等质量控制,使得大坝填筑碾压质量全面满足设计要求。Nazixia Hydropower Project is with a concrete face gravel-fill dam. Currently, the embankment filling is fulfilled. During the embankment filling, the effective quality supervision system is established and implemented. Through the quality control of overburden excavation, material selection, unloading, spreading, water spraying, roller compaction, and measurement of dry intensity of the gravel materials for the main embankment, quality of the roller compaction of the embankment filling satisfy the design requirements.
