Sažetak
The objective of this work is to research the influence of injected heat flux on determination of ground thermal properties by thermal response test. The experimental approach is used to conduct the research and includes two different TRT's conducted, in duration of 72 hours each, with different average injection heat fluxes: 4.43 kW and 7.64 kW. The entire measurement procedure consists of pressure and hydraulic tests, undisturbed ground temperature measurement, TRT and ground recovery monitoring. The measurement results are analysed using infinite line source model (ILS). The results show that the use of higher injection heat flow reduces the influence of the ground's inhomogeneity on the results obtained.
