However, radical changes in the environment, including geological, as a result of construction and human activities pose a serious threat to the maintenance of stability of monuments. Among the ways to protect the designs and materials of ancient buildings a very important role is played by questions of temperature and humidity, the choice of the optimal parameters of the medium and how to maintain them.The article provides a comparative analysis of the physical and mechanical properties of soil and ground water of mausoleum Arystan-Bab for 1984, 2004 and 2014.
