【摘要】：可溶盐在一定温湿度条件下在土遗址基体反复溶解—结晶是造成土遗址本体病害的主要原因。本文考察了荆楚故地大型古墓熊家冢土遗址本体的含盐情况,对土遗址取样并进行XRF、XRD、XPS、TEM及离子色谱等方法表征并分析其盐分种类及含量,结果表明,熊家冢实验区域取样基底土中主要含有的成盐阳离子有Na~+、K~+、Mg~(2+)、Ca~(2+)等,阴离子有SO_4~(2-)、NO_3~-、Cl~-等,其中Cl~-含量较少。遗址基体中盐分主要以钙芒硝及水合氯化钙形式存在着。熊家冢土遗址取样与所含盐分分析为其遗址保护提供了必要的参考与基础。
[Abstract]:The dissolution and crystallization of soluble salt in the matrix of the earth site under certain temperature and humidity are the main causes of the body disease of the soil site. In this paper, the salt content in the body of Xiongjiazhuang earth site, a large ancient tomb in Jingchu, was investigated. The samples were taken and characterized by XRF XRDX XPS Tem and ion chromatography. The results showed that the salt species and contents of the samples were analyzed. In Xiongjiazhuang experimental area, the salt forming cations mainly contained in the subsoil of Xiongjiazhuang are Na ~ (+) K ~ (2 +) mg ~ (2 +) ~ (2) and so on, and the anions are so _ (4) ~ (2) ~ (2) no _ (3) ~ (-) -Cl ~ (-), among which the content of Cl ~ (-) is relatively small. The salt in the base of the site mainly exists in the form of glauberite and hydrated calcium chloride. The sampling and salt content analysis of Xiongjiazhuang site provide the necessary reference and foundation for the protection of Xiongjiazhuang site.
