Using ILS mathematical model and measurements for detailed evaluating results of thermal response tests

This paper deals with problems of evaluating TRT experiment results, related to determining some essential parameters of a rock massif (mainly a thermal conductivity λ and a thermal borehole resistance R
_B
). In practical use, these parameters are usually prescribed by tables or measured in-situ in this case. This paper also includes some detailed mathematical background for an ILS model (an infinite line-source model). For comparison, there are some described and discussed results from very interesting locality of Lysá hora (1323 meters above the sea level), where the TRT experiment was realized in September 2011.
