摘　　要：尼尔基水利枢纽工程沥青混凝土心墙砂砾石主坝,是决定施工工期、进度和工程投资的主要建筑物之一,因此主坝的合理设计至关重要。经比较,采用碾压式和浇筑式沥青混凝土心墙砂砾石坝较为经济合理,且适合东北地区的气候条件,坝顶部上游面护坡首次采用台阶式现浇混凝土护坡形式。The main earth-rock dam with asphalt concrete core is one of major structures which decide construction period, schedule and project investment in Nierji hydroproject. So the rational design of main dam is extremely important. With comparison, earthrock dam with rolled and cast asphalt concrete core is more economic and rational. Meanwhile, it is suitable for the climate of northeast area. It is the first time that bench concrete slope protection is used for crest upstream slope protection.
