Combining with a geo-thermal response test project in North China,the key issues of geo-thermal response test are analyzed and the test methods and steps are illustrated in detail.Vertical double U-tube test wells are taken,and the comprehensive thermal parameters of ground-source are received through field test of two test wells with depth of 120m.Furthermore,the original ground temperature and the inlet and outlet water temperature response curve of the underground heat exchanger are also obtained,which are used to determ ine the heat exchange quantity of per well depth and other parameters.
