摘　　要：水是夯土城墙风化劣变的重要因素之一。由于大气降水的冲刷和渗流作用,使夯土城墙不断地受到侵蚀甚至是坍塌。以吉林市龙潭山城遗址西段夯土城墙为研究对象,为了系统研究水分对其劣变的影响,土样采用常规物理性实验、X-射线衍射、扫描电镜测试等实验方法,研究夯土墙的土壤孔隙结构特征变化,对比分析了水分对不同深度夯土段的风化影响。结果表明:自地表水下渗至地下水的过程中,夯土风化程度由大到小排序为地下水作用区、孔隙渗水区、毛细水作用区、裂隙渗水区。Moisture plays a critical role in the weathering and deterioration of rammed earth walls.The erosion and infiltration lead to the degradation and even collapse of rammed earth walls by atmospheric precipitation continually.Focusing on the western section of the rammed earth wall at the Longtanshan Site in Jilin City,Conventional soil physical experiments,X-ray diffraction analysis,and scanning electron microscopy were employed to examine the changes in the pore structure of soils within the rammed earth walls,systematically assessing the impact of moisture on the deterioration of rammed earth city walls.we conducted a comparative study of the effects of moisture on the weathering of rammed earth at varying depths.The findings indicate that as water infiltrates from the surface to the groundwater,the degree of rammed earth weathering from high to low are,the groundwater-actioned zone,by the pore water infiltration zone,the capillary water-actioned zone,the fracture infiltration zone.
