Rockfall mass rating

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. Web6 Dec 2024 · This article presents an approach to rockfall hazard assessment for rocky slopes based on a previously published rockfall hazard methodology. The original method is appropriate to high alpine rocky slopes exposed to large scale deformations. It evaluates the parameters related to the geomechanical characterization of rock mass, indications of …
