High Energy Rock Fall Embankment Constructed Using a Freestanding Woven Wire Mesh Reinforced Soil Structure--Recent Experience in British Columbia, Canada

This paper will discuss the site history, design, installation, and recent post-construction experiences with an 8m high rock fall embankment built on BC Highway #1 (Trans-Canada Highway) near Boston Bar, British Columbia. There have been over 60 recorded rock fall events at the site since the highway was constructed in 1958. Numerous attempts have been made since 1958 to mitigate the rock fall hazard using different techniques with limited success. The new rock fall embankment was built using a double sided, woven wire mesh, gabion-faced, mechanically stabilized earth system. The structure was designed to withstand a maximum rock fall impact energy of 10,000kJ. The reinforced soil embankment has a maximum height of 8m, with a maximum base width of 7m.
