The geotechnical thermal physical properties are of great significance for the design of ground source heat pump (GSHP) system. In this paper, geotechnical thermal response test based on lineal heat source model was used to evaluate the geotechnical thermal physical properties of one GSHP project in Weinan city, Shaanxi province. Result of the 58-hour test data analysis showed that the thermal conductivity of soil in this area was 2.16 W/(m∙K), the specific heat capacity of soil l in this area was 2.39 MJ/(m3∙K), the heat exchange per meter of the single U pipe ground-coupled heat exchanger was 45 W. This work can provide some guides for further design and construction.
