摘要
岩土材料的导热系数是一个重要的热物理参数,是很多工程技术问题的设计和研究所必须涉及到的。本文中采用QTM快速热导测试仪分别测试了某海滨地区不同深度淤泥土的导热系数,并对所测得的数据进行拟合,得出拟合曲线方程,进而分析导热系数与温度及含水率之间的关系。试验结果表明,淤泥土的导热系数随着温度的升高而减小,随着含水率的增加而增大。
The thermal conductivity of geotechnical materials is an important parameter of thermal physics,which is widely used in many engineering design and research.In this paper the QTM fast thermal conductivity tester was used for testing the thermal conductivity of mucky soil in different depths in a coastal area,and analyzed the relationship of between thermal conductivity and temperature and moisture content by fitting the datas and drawing the curve fitting equation.The experimental results show that the thermal conductivity of mucky soil decreases with the increase of the temperature,but increases with the increase of the moisture content.
