Abstract
A rock fall barrier including a plurality of support posts and a deformable net spanning the plurality of support posts. Each support post includes: a base fixed to a sloped surface; a first arm pivotally coupled to the base at a first hinge; a first hinge brake for providing friction at the first hinge to provide controlled resistance against pivotal rotation of the first arm relative to the base; a second arm pivotally coupled to the first arm at a second hinge; and a second hinge brake for providing friction at the second hinge to provide controlled resistance against relative pivotal rotation between the first arm and the second arm. A guy wire system is attached to the distal end of each support post on one end and anchored to the sloped surface on the other end. The guy wire system includes upper guy wires having cable brakes.
