Rockfall is the falling of detached rock mass from a hill slope under the influence of gravity. Rockfall from potentially fractured rock slopes represents hazards to the traveling public. With aging of the roadway system, these highway rock cut slopes deteriorate because of weathering. Consequently, the potential for rockfall and rockslides increases.
Rockfall Mitigation Methods– Mitigation is done by providing rock fall barrier with fixed or hinged connection. The barrier has high tensile wire mesh and brake system which dissipates energy of falling rock mass. Depending upon material involved, it is rock fall & debris flow barrier. Rockfall protection can be either active or passive. Their main function is to prevent and control rocks and debris from falling.
