USE OF ROCK MASS RATING (RMR) VALUES FOR SUPPORT DESIGNS OF TUNNELS EXCAVATED IN SOFT ROCKS WITHOUT SQUEEZING PROBLEM
Effect of the rock material strength on the RMR value and tunnel support designs were investigated within this study including site works, analytical and numerical analyses. It was found that rock material strength effect is quite limited in the RMR method to determine an accurate rock mass class to...
