I-80 Rockfall Mitigation Photo

Stabilization

Stabilization consists of securing and/or reinforcing the rockfall zone to prevent rocks from moving. Available methods include targeted rock dowels or anchors, cable lashing, anchored mesh, polyurethane resin "grouting", shotcrete and buttressing. The photographs below illustrate two types of stabilization techniques: rock dowels and anchored mesh systems. The use of shotcrete and buttressing for the stabilization of shear zones along rock slopes is also a common method. Installation of these designs generally requires specialty contractors with experience executing the methodologies and working on steep slopes where access can be challenging. Permanent mechanical systems require periodic monitoring and maintenance, which should be considered in overall project costs.
