为研究沥青混凝土心墙的变形性能，对德国了恩（Ｄｈｎｎ）主坝和上游坝，通过安装在心墙和观测竖井中的仪器进行了长期观测。从对初期蓄水期和运行期心墙受力和变形情况的分析，得出的结论是：沥青心墙的变形特性主要受坝肩影响；为减小心墙的剪应变，应改善坝体的沉降性能；不赞成减小心墙上部宽度。总之，沥青混凝土心墙可以用于坝高大于１００ｍ的高坝。
To study the deformation behavior of asphalt concrete core walls, long-term observations were made of the main Dhnn dam and the upstream dam in Germany using instruments installed in the core wall and observation shaft. From the initial storage period and the operation of the heart wall stress and deformation analysis concluded that: the deformation of asphalt core wall is mainly affected by the impact of the dam; to reduce the shear wall of the heart wall should be improved dam Settlement performance; not in favor of reducing the width of the upper part of the heart wall. In short, asphalt concrete core wall can be used for dam height greater than 100m dam.
