Web2 Feb 2013 · RMR classification is carried out to determine the geomechanical condition of slope rock mass and Rockfall Hazard Rating System (RHRS) is applied for identifying the … WebThe rock mass lies on the upper slope of the houses subjected to rockfall (see Fig. 2-a). The analysis considers the SW face of the slope looking towards the houses (Fig. 2-b). Accordingly, the slope's dip/dip direction was recorded as 85o/205oin the field.
