摘　　要： 完成热响应试验后关闭加热器,维持循环泵和数据采集系统运转,即可进行热恢复试验。根据热流叠加原理和线热源理论,得出传热介质平均温度随开启加热器开始计时的时间与热恢复试验时间之比的自然对数呈近似线性关系。通过工程实例阐述热恢复试验现场试验方法和数据处理方法,验证用其确定岩土导热系数和钻孔热阻的准确性和实用性,为用热恢复试验确认或检验岩土热响应试验成果提供理论依据和实例。 Shutting off the electric heater, keeping the operation of circulation pump and data acquisition system after thermal response test （TRT）, thermal recovery test （TReT）can be carried out. According to heat flux superimposing principle and line heat source theory, it is concluded that the average temperature of the heat transfer fluid is approximately linear with the natural logarithm of the ratio of the time at which the heater is started and the heat recovery test time. The field test method and data processing method of heat recovery test are stated through a case study, which verifies the accuracy and practicability for confirming heat conductivity of rock and thermal resistance of the borehole, provides theoretical basis and example for thermal recovery test to confirm or test thermal response test result of rock.
