摘　　要：为了解辽上京遗址皇城城墙和汉城城墙夯土制作材料成分及其性能,采用XRD物相分析和扫描电镜结构与元素分析方法,分析了辽上京皇城和汉城夯土样品的组成成分,结果表明,皇城夯土为粘土中加入石灰夯筑而成,汉城夯土仅用粘土夯筑。测试了皇城夯土和汉城夯土的理化性能,结果显示皇城夯土在抗雨水侵蚀能力、力学性能及可塑性等方面均优于汉城夯土。In order to find out composition and properties of rammed earth in Liao upper capital, XRD and scanning electron micro- scope （SEM） were used to analysis the sample from the wall of imperial city and Han city. The experimental results showed that the rammed earth from imperial city were rammed by clay with lime, and the rammed earth from Han city were rammed only by clay. We tested the physical and chemical properties of rammed earth. The results showed that in anti rain erosion ability, mechanical properties and soil plasticity etc, the rammed earth from imperial city were better than Han city.
