Developing Best Practice for Helicopter Sluicing for Rockfall Mitigation following the 2016 Kaikoura, New Zealand, M 7.8 Earthquake
Publication: Geo-Extreme 2021
ABSTRACT
The November 2016 M 7.8 Kaikōura earthquake caused major disruption of, and significant damage to, the key transportation corridor on New Zealand’s South Island. The national road, State Highway 1, and rail, Main North Line, were severed by nearly 1M m3 of rock and slope debris from more than 100 landslides and debris flows. Helicopter sluicing was selected as a key mitigation method to remove unstable debris from earthquake-damaged slopes and enable access for construction equipment and staff. The overall sluicing program is described. Lessons learned from sluicing at Kaikōura are being developed together with other New Zealand wide experiences to establish “best practice” principles and processes for future use.
