Monitoring of the temperature-moisture regime of rock dwellings in Brhlovce village (Slovakia)

摘要

The aim of the paper is to evaluate the weathering and the damage of rock dwellings in Brhlovce village (Slovakia) based on terrain research of the natural rock mass as well as on laboratory research. A new principle of a sensor for monitoring of moisture in the porous materials/volcanic tuffs/ is presented. The sensor principle is based on hot ball method. A hot ball method is used for measuring thermal conductivity. In fact, the thermal conductivity of porous structure is dependent on moisture content in pores e.g. when pores are filled by air/vapour, water or ice. Additionally it is dependent on thermodynamic conditions like temperature gradient and temperature history. Laboratory research of moisture regime was studied using moisture sensor that was finally embedded into rock mass directly. In situ monitoring of the temperature-moisture regime of volcanoclastic rocks where the dwellings were carved out has been running more than one year. The temperature/moisture regime is monitored from October 2011 up to nowadays.
