Influence of a gallery on the stresses in the surrounding rock salt

Abstract

This report deals with a numerical analysis of the gallery induced loading. The analysis (finite element program ANSYS) deals with the mechanical loads (stresses and deformation) caused by the rock pressure at the location of the gallery. Most of the anlayses have been performed for a period of 10 years while some cover a period of 100 years. The numerical results indicate that the region where the stress distribution is effected by the presence of the gallery depends strongly on time elapsed since its excavation. Ten years after excavation the region where the equivalent stresses are larger than 1 MPa is extended to {rho}=18. For 50 and 100 years the region is extended to {rho}=27 and 32. The effect of the gallery on the hydrostatic stress component is not so pronounced. The region in which the hydrostatic stress component deviates more than 1 MPa in the time periods 10, 50 and 100 years is limited to {rho}=7, 12 and 15. (orig./HP)
