| Popis: | From the examination of rock physical parameters&rsquo changes of compressive strength, shore hardness, water absorption, P-wave velocity with increasing freeze&ndash thaw cycles, correlations of these parameters were investigated. Rock samples were collected from Ny-Å lesund region in Norway. As compressive strength and shore hardness inherently have high uncertainties due to inhomogeneous rock composition and internal fissures and cracks, only the relationship between water absorption and P-wave velocity revealed high correlations, providing meaningful linear fitting equations. From the correlation analysis results and clear trends of increasing water absorption and decreasing P-wave velocity with increasing freeze&ndash thaw cycle found in part one of the companion study, prediction equations of future changes of rock physical parameters are proposed using P-wave velocity or water absorption. In addition, future rock weathering grade changes with time can be predicted from estimation of water absorption or P-wave velocity change due to freeze&ndash thaw cycles. |
