RMR in Urban Tunnel with Risk Factor of Collapse

RMR is a largely accepted rock classification method for design of support system in domestic tunnels. However, the RMR system, which is based on geological survey during design stage of tunnel, can not present the real ground conditions accurately. In this study, authors suggests a concept of We...
