摘　　要：坝基处理是土石坝施工的重要前提,高沥青混凝土心墙坝对坝基完整性、防渗级别提出了更高的要求,为了满足设计规范要求及加固坝基的目的,结合某高沥青混凝土心墙坝坝基灌浆施工技术实例,采用“固结灌浆→帷幕灌浆”坝基灌浆手段,克服了地质缺陷影响,达到了高沥青混凝土心墙坝坝基技术要求,提出高沥青混凝土心墙坝坝基处理的建议和展望。Dam foundation treatment is an important precondition for earth-rock dam construction. High asphalt concrete core dam sets higher requirements for dam foundation integrity and seepage-proof level. In order to meet the requirements of design specifications and reinforce dam foundation, combined with the construction technology example of dam foundation grouting for a high asphalt concrete core wall, the dam foundation grouting method of "consolidation grouting curtain grouting" is adopted to overcome the influence of geological defects and meet the technical requirements of dam foundation for high asphalt concrete core wall. Suggestions and prospects for dam foundation treatment of high asphalt concrete core wall are put forward.
