Abstract

The distribution of temperature and rock pressure stresses with regard to the temperature factor around underground radioactive waste (RAW) repositories in the underground space is considered. The geological formations taken are blue clays deposited in the Northwest region of Russia. The problem is solved by the finite element method. Influence of a temperature factor on the stress-strain state of the support-mass system was found out. The surface elevation from the temperature in the RAW chambers has been established. The analysis of the influence of the RAW chambers on each other has been made. The patterns of horizontal and vertical stresses distribution along the chamber axis were found.
