摘　　要：尼尔基工程主坝碾压式沥青混凝土心墙有效施工时间短、强度大、气候条件恶劣,前期防洪形势严峻。施工中,对配合比的确定,沥青混凝土制备、摊铺、碾压设备及工艺的选择都十分重视,而且对每层压实后的沥青混凝土均进行质量检验,创造了优良率100%的好成绩,为严寒地区碾压式沥青混凝土心墙施工积累了经验。There is a short paving season, high intensity, severe weather conditions and high pressure in flood at the start of construction in the compacted asphaltic core of Ni＇erji project. Stressing on mixing design, hatching, placing, equipments and techniques of compaction in construction. To check and measure quality every, layer after compaction and gained a high quality in construction. Enriching experience on the construction of compacted asphaltic cores in cold conditions.
