Abstract: Geotechnical thermal parameters, which directly represent the formation thermal response characteristics, are major factors influencing the design of ground source heat pump system. The thermal response test is one of the important means to obtain the parameters. According to the different geomorphic units in Shenyang City, 5 groups of thermal response tests are carried out for 3 typical geotechnical combinations to analyze the comprehensive thermal response characteristics as initial temperature, complex thermal conductivity and ground temperature recovery time of formation. It is suggested that ground source heat pump should be developed first in the western region of the city. The above results will provide references for the planning and utilization of ground-source heat pump system in Shenyang.
