摘　　要：以苏州地区某地块项目地源热泵工程为依据,采用恒热流方法对现场单U和双U型地埋管分别进行了岩土热响应试验.通过该试验获得了该项目现场地质情况和岩土体热物性参数,同时计算出各种工况下地埋管换热性能并进行分析,得出该地区的地下土壤平均导热系数为2.02 W/(m·K),双U型地埋管换热器比单U型地埋管换热器的换热性能约高15%.This paper uses the constant heat flux method for thermal response test of sipipe respectively which is based on ground source heat pump engineering project in Suzhou.Through this experiment, the geological condition of the project and the thermal physical parameters of rock and soil are othe performance of the ground heat exchanger under various operating conditions are calculated and analyzed.It is conclu-ded that the average thermal conductivity of the soil in this area is 2.02 W/ （ m· K）, and that the heat exchanger perform-ance of double U pipes is about 15% higher than that of single U pipes.
