摘　　要：牙塘水库沥青混凝土防渗心墙配比优化试验研究从骨料矿物化学成分构成分析入手,以SiO2含量作为关键衡量指标进行配比优化,并对优化配比从水稳定性、冻融两个指标进行检测,进而对沥青混凝土的弯、拉、压力学指标、变形、渗透等指标进行综合检测。优化配比又通过工程实际运用达到了试验指标的结果,为沥青混凝土心墙配比提供了新的配料方式。This paper conducts an experiment study on the asphalt concrete core wall mixture ratio optimization of Yatang Reservoir through analysis of the mineral chemical components of the aggregate. It optimizes the mixture ration using the content of SiO2 as the key measurement index, and tests the stability and freeze thawing cycle of the optimized mixture ratio. It also investigates the me- chanical properties of bending, pushing, pressure, deformation and leakage of the asphalt concrete. The optimized mixture ratio is proved to achieve the expected results through practical implementation. As a result,the paper provides a new mixture ratio mode for asphalt concrete core wall.
