摘　　要：研究百米级浇筑式与碾压式沥青混凝土心墙坝的应力应变性态对沥青混凝土心墙高坝发展具有重要意义。通过平面有限元分析表明:大坝的应力应变性态,明显受控于坝体填筑材料的性状,而受心墙沥青混凝土材料性质影响较小,采用两种心墙材料所得大坝的应力变形规律变化不大。Study stress and strain of one hundred meters pouring and rolling compacted dam with asphalt concrete core is of great significance to the development of high dam with asphalt concrete core. Through plane finite element analysis,the results show that the dam stress and strain state obviously controlled by filling of the dam material properties,and stress and strain is less affected by the properties of asphalt concrete,stress and deformation rules did not change by two kinds of core materials of the dam.
