摘要
研制了两种岩土热物性测试仪,介绍了线热源斜率法、双参数估计法和三维数值模型法3种测试热物性的方法。建立了一个三维数值模拟模型,分析了测试时间、计算开始与结束时间、比热容等因素对导热系数、热阻的影响。
Develops two kinds of test devices for soil thermo-physical property test, and presents three kinds of thermo-physical property test method including slope determination method, two variable parameter fitting method and three dimensional numerical model method. Develops a three dimensional numerical model, and analyses the effect of testing time, starting time and ending time of calculation, and volumetric specific heat on the thermal conductivity and thermal resistance.
