摘　　要：以工程场地测试孔内岩土体垂直分布的热物性参数为研究对象。在传统热物性测试仪器中加入分布式光纤测温系统，进行岩土体初温测试和热物性测试，测定不同深度岩土体初温和加热试验中不同深度循环流体平均温度，并与传统测试结果进行对比分析。结果显示，分层热物性测试结果较为准确，可分析岩土体垂直方向温度分布，进而得出地埋管换热器在垂直方向上导热系数和传热系数。The thermophysical parameters of the vertical stratified rock and soil mass in the test hole were taken as research object. The distributed optical fiber temperature measurement system was added into the tranditonal thermophysical property testing instrument to measure original temperature and thermophysical properties of rock and soil mass. The original temperature of rock and soil mass in different depth and the average temperature of circulating fluid in different depth under heating test were measured, and were compared with the traditional test results. The results showed that stratified thermophysical property testing results are more accurate, which can be used to analyze the temperature distribution in the vertical direction of rock and soil mass, and get the thermal conductivity and heat exchange coefficient in the vertical direction of buried pipe heat exchanger.
