In order to determine the coefficient of the underground thermal physical properties of jintan, changzhou, and to provide theoretical basis for the development of shallow geothermal energy, distributed thermal response test (DTRT) and active heating optical fiber thermal response test (ATRT) were used to monitor and evaluate the thermal conductivities of strata at different depths in this area, and then monitoring results of different technologies were compared. The experimental results show that compared with traditional TRT, DTRT based on DTS technology can realize the distributed measurement of thermal conductivity of all soil layers. Moreover, ATRT, which can also obtain relatively reliable thermal conductivity, takes less time and consumes less energy compared with TRT and DTRT, showing a great potential in ground temperature monitoring.
