Rmr stand up time
WebBased on the correlation between the RMR and Q systems, the stand-up time for an unsupported span was extended for the Q system , as shown in Figure 1. 5.2. Rock Load. In underground excavations, generally, the load on installed support is known as rock load. Webstand-up time. Stand-up time is obtained by entering the RMR value and span width on the stand-up time graph by Bieniawski in 1989. This study aims to determine the stand-up time value and compare it with the estimated time of actual support installation in the field, as well as determine the level of tunnel stability. Based on the
