ABSTRACT: The authors have proposed and discussed temporary storage of low temperature materials such as LNG, LPG and frozen food in openings excavated in rock mountains. In this study, strength and deformation of some types of rocks were examined after receiving thermal hysteresis of low temperatures. The effects of the amount of thermal hysteresis, temperature range, porosity, etc. on strength and deformation of rocks were discussed. Using the results of the tests, temperature and stress distribution around openings were analyzed. Then the effect of thermal hysteresis of low temperatures on thermal behavior of the rock mass around openings was discussed.
