摘　　要：与常规土质防渗体土石坝相比,沥青混凝土防渗土石坝具有防渗性能好、施工受气候影响小、抗冲蚀能力强、不存在水力劈裂破坏问题等优点,在缺乏合适防渗土料或寒冷、严寒采用土料施工困难的地区得到广泛应用。以云南省弥勒坝水库为例,对沥青混凝土心墙的型式选择、沥青混凝土的技术指标的确定,布设方案、心墙厚度、心墙与基础和岸坡的连接设计等进行了分析论述。Compared with common earth-rock dam,asphalt concrete dam,with its obvious advantages,for example highly impervious performance,less affected by climate,high ability of erosion resistance,free from hydraulic fracturing,etc,is widely used in location with little proper materials or where the cilmate is too severe to use common earth-rock materials.This paper will take Mile dam for example to illustrate how to choose the right type of asphalt concrete core wall,select proper qualified asphalt concrete,take the appropriate layout programme,plan the suitable thickness of core wall,design proper links between core wall,baseline and bank slope and other key points in designing a high qualified asphalt concrete dam.
