摘　　要：浇筑式沥青混凝土心墙坝由于具有浇筑期短、变形协调性好、易于冬季施工和方便管理等优点得到广泛的运用。本文对贵州省者岳水库沥青混凝土心墙坝的浇筑材料分别进行室内配合比实验和场外物理性能试验,通过对试件的孔隙率分析、水稳定性分析以及渗透性分析,确定在冬季低温条件下沥青混凝土最优的施工配合比,从而为大坝心墙浇筑提供合理经济的指导。The pouring asphalt concrete core wall dam has been widely used due to its short pouring period,good deformation coordination,accessible winter construction and convenient management.In this paper,the indoor mixing ratio experiment and the physical performance test of the asphalt concrete core wall dam of Zheyue Reservoir in Guizhou Province were carried out respectively.The optimal construction ratio of asphalt concrete under low temperature conditions was determined though the comprehensive analysis on the porosity,water stability and permeability which provides reasonable and economic guidance for concrete placement of dam core wall.
