摘　　要：尼尔基水利枢纽工程的导流明渠段坝为振捣式沥青混凝土心墙,全长258.46 m,厚0.5 m。其施工工序包括碱性骨料加工、混合料拌和和现场摊铺、振捣、温度控制等。采用振捣式沥青混凝土心墙解决了浇筑式的分层、离析问题,使心墙的密实性和防渗性更加安全可靠,而且施工方便、简洁、效率高、施工成本低。尼尔基工程振捣式沥青混凝土心墙的施工技术可供类似工程参考。The diversion channel of Ni＇erji Water Control Project is a vibrated asphalt concrete core wall with the length of 258.46 m and the thickness of 0.5 m. Its construction processes, including alkaline aggregate processing, mixing the materials and site paving, vibration, temperature control, etc. Use vibrated asphalt concrete core wall for pouring which the solute stratification, segregation, so that the dense core of impermeable nature and more secure, reliable, convenient, simple, high efficiency and low cost of construction. The construction technique of vibrated asphalt concrete core wall of Ni＇erji Water Control Project can be used for reference in similar projects.
