摘要
本研究采用SEM-EDS和XRD分析方法,对獾子冢搬迁车马土体土样进行分类定性,对土样的元素成分、黏粒矿物组成进行分析。针对车马土体最典型的裂纹病害,对土样进行物理力学性质分析和试验,特别是进行了不同初始含水量下土样的失水收缩模拟实验,对土壤的线收缩率的变化进行了对比研究。此外对土样易溶盐、酸碱度、有机质含量也进行了测试。试验研究不仅可以为后续修复工作的科学实施和保存展示的顺利展开奠定基础,也为探讨比较规范的土质类文物的分析方法和试验方案提供了案例借鉴。
In order to identify the soil type, composition elements, and clay mineral constitution, both SEMEDS and XR.D analyzing methods are used. Four soil specimens with different water consumption ratios are tested to compare the variations of the specimen＇s contraction ratio. The content of easily dissolute salts, organic stuff, and pH value of the soil is also measured. These research experiments will provide an example for later systematic analysis of the soil as well as a referential guideline for later restoration work.
