Abstract

The thermal conductivity of rock is one of the key parameters in geotechnical engineering. The thermal conductivity of rock is affected not only by rock properties，such as mineral composition and porosity，but also by the geological condition of rock，such as temperature and water saturation. To reveal the effect of temperature and water saturation on thermal conductivity of rock，the thermal conductivity of sandstone at different temperature and water saturation was measured by self-designed experimental system. The results indicate that，in the temperature range of －80 ℃–90 ℃，the thermal conductivity of sandstone decreased with the increase of temperature，and the reduced rate varies with the rock，namely grit stone maximum，fine sandstone second，and siltstone minimum. Moreover，it is found that the thermal conductivity increased with the moisture content，but its growth rate decreased with the growth of environment temperature. Finally，it is shown that the thermal conductivity of saturated sandstone increased with the temperature and there was significant mutation near 0 ℃. Meanwhile，it was revealed thatthe reason of mutation is phase transformation of pore water.
