摘要 在埋地换热器圆柱热源模型的基础上采用参数估计法建立了一套可用于现场确定土壤热物性的方法。结合地源热泵系统单井热响应测试实验,计算了地下岩土热物性参数,模拟了管内流体平均温度随时间变化规律,与实验值比较,发现该方法较线热源法更加接近实际。 Ground thermal properties have great influence on the number and the depth of boreholes, and thereby on the capital investment in ground source heat pump（GSI-IP） system design. A method to determine ground thermal properties used by in-situ field thermal response tests was established based on the cylindrical heat source model. The thermal properties were obtained. The average temperature of circulating water in the loop is simulated with time, and is compared with test value. It is showed that the present model is available.
