Passive protection systems (additional intercept small rockfall layer steel wire mesh) by wire rope or ring network, fixed system (anchor, anchor rope, dock and support rope), pressure ring and steel columns four major sections constitution. 1 Introduction passive protection systems (additional intercept small rockfall layer steel wire mesh) by a ring network, the fixed system (anchor, anchor rope, dock and support rope), pressure ring and steel columns four major sections constitution. Which intercept network section includes major impact structure ring network and intercept small rockfall wire grill, fastening systems section contains anchor, anchor rope, dock and support rope. When rockfall stopped stone net impact load generated by the first portion of the web through the buffer to be dissipated, while in the mesh is deformed by the impact displacement will pull the entire system involved in the force, a part of the load by stitching within the span ropes, supporting rope to the steel columns, anchor rope pass and cut, the other part of the load adjacent to the sides of the structure through the safety net of successive passes, thereby mobilizing other across the energy dissipation structure force participation, and eventually all of the remaining load transfer to stabilize the formation.
