为了研究干密度、含水率和 NaCl 含量对遗址土热劣化的影响，采用 Hot Disk 热常数分析仪对良渚遗址、交河故城遗址和通古斯巴西古城遗址的遗址土重塑样进行了热物理参数的测试，分别确定了遗址土的导热系数、热扩散系数和体积比热随干密度和含水率的变化关系。对通古斯巴西古城遗址重塑样掺入了不同含量的 NaCl，研究了含盐量对遗址土重塑样导热系数的影响。结果表明，当含水率与干密度增加时，3种遗址土的导热系数均呈线性增长，热扩散系数和体积比热也随着含水率与干密度的增加而增大；相同条件下3种遗址土的热物理参数存在差异，良渚遗址的较大，交河遗址的较小，通古斯巴西古城的居中总体上与土中 SiO2含量成正相关关系。当干密度与含水率一定时，掺入 NaCl 增加了遗址土的导热系数。

X In order to study the influence of dry density, water content and soluble salt content on the thermal deterioration of earthen monuments, Hot Disk heat constant analyzer is used to test the thermal parameters of soils from different earthen monument sites such as Liangzhu, Tunguska Brazil and Jiaohe. Meanwhile, Tunguska Brazil soil is concentrated with different concentrations of NaCl, then the thermal conductivity coefficient is measured to analyze the influence of salt content. The results show that the thermal conductivity coefficients of three types of soils increase linearly with increasing water content and dry density. The thermal diffusion coefficient and specific heat volume are also increased with increasing water content and dry density. The thermal parameters of earthen monuments soils are found to be correlated positively to the SiO2 content in soil. For the above-mentioned three sites soils, their thermal parameters are different under same conditions; the Liangzhu soil is the greatest; Tunguska Brazil soil is second and Jiaohe is the least. In addition, concentrated NaCl increases the thermal conductivity of soil.
