【摘要】：为探讨不同遗址土质对可溶盐危害影响的关系,以秦陵百戏俑坑为对象,对百戏俑坑包括温湿度等赋存环境、含水率、含盐种类、含盐量、土质及本体等进行调查分析。根据调查结果选取密度和粘粒含量两个影响土质的重要因素,制作不同密度及不同粘粒含量的模拟块进行温湿度循环实验,探讨这两个因素对遗址盐害的影响。从实验结果中得知,当这两个变量发生变化时,土块盐害程度呈现随着密度和粘粒含量的增大呈现先下降后升高,最后降低的趋势。并将实验得出的盐害规律与百戏俑坑土质对照,评估与讨论百戏俑坑的盐害程度及盐害风险。
[Abstract]:In order to explore the relationship between soil quality of different sites and the harm of soluble salt, taking the Baixi Terracotta Warriors Pit in Qinling as an object, including the environment of temperature and humidity, moisture content, salt species, salt content, etc. According to the investigation results, two important factors, density and clay content, are selected to influence soil quality, and simulated blocks with different density and different clay content are made to carry out temperature and humidity cycling experiments. The effects of these two factors on the salt damage of the site are discussed. It is found from the experimental results that when the two variables change, the salinity damage degree of the soil block decreases first and then increases with the increase of density and clay content. Finally, the trend of decreasing was analyzed. The salt damage law was compared with the soil quality of Baixi Terracotta Warrior Pit, and the salt damage degree and risk of Baixi Terracotta Warrior Pit were evaluated and discussed.
