The Qingdao Blue Silicon Valley region has abundant geothermal resources for its special geological structure. However, due to the low degree of exploration and lacks comprehensive evaluation, the utilizing form of geothermal resources is single, and the high-quality geothermal resources are serious waste. In this paper, geotechnical thermal response test based on lineal heat source model was used for field test to study the geotechnical thermal physical properties of buried test holes in the Blue Silicon Valley region. Result of the 48-hour test data analysis showed that, the calculated thermal conductivity of the soil was 2.278 W/(m∙K), which ensures the heat transfer capability of the ground source heat pump. Furthermore, the summer conditions were simulated by using column-heat-source model, it turn out that the fluid temperature trends were similar with the experimental ones. The simulated inlet and outlet temperatures were 35.1°C and 30.4°C, which were in good agreement with the experimental temperatures of 35.1°C and 30.8°C. This work may provide some guides for the analysis of the thermal physical properties of the ground source heat pump and the integrated development of the Blue Silicon geothermal resources.
