Assessment of rockfall risk along mountainous road with Rockfall Hazard Rating System (case study of Chalus Road)

Abstract:

The Rockfall Hazard Rating System (RHRS) was design to proactively address the issue of rockfall for road cuts and rail lines. It is taking into account a range of diverse aspects and further more the system is useful as a screening, allowing high-risk slopes to be quickly identified by a preliminary rating. As a system of Highway rock cut stability assessment in rock mass, this method has been applied along with other methods of rock slope stability assessments in Chalus Road Rockfall Project.  In this paper the method, suggestions and conclusions, regarding to apply of it to rockfall hazard rating along
