Using TRT for determining the essential thermal parameters of rock massif

摘要

This paper deals with problems of thermal response test (TRT) in connection with determining the essential borehole parameters, mainly thermal conductivity and borehole resistance. In practical use, these parameters are usually prescribed by tables; in case of larger buildings, it is required to measure them in situ. This paper also includes detailed mathematical background, focused on the TRT. For comparison, there are some described and discussed results from several experimental TRT measurements, done in year 2011 in the Ostrava region.
