SUMMARY:RTSA NZ Chapter Event (Webinar): Innovating in response to the 2016 Kaikōura earthquake: Modular rockfall protection wall development
DESCRIPTION:The landslides caused by the 2016 Kaikōura earthquake presented many challenges for the NCTIR geotech design team working on mitigating the rockfall hazards that affected the narrow coastal rail and road corridor. In a few locations\, site conditions meant that there was not enough space to use the traditional rockfall protection solutions. \nA new type of rockfall protection wall was designed to be used within these narrow spaces. This modular rockfall protection wall uses readily available components\, including a modified version of the concrete sea wall blocks used on the NCTIR project together with an upslope\, energy-absorbing layer of sand and rock-filled gabion baskets. \nTo satisfy engineering design requirements\, a series of impact tests were carried out at a vehicle crash-test facility to demonstrate the capacity and performance of the wall. It performed successfully\, and two walls have since been constructed to provide rockfall protection for the road and rail north of Kaikōura. \nSpeaker: Rori Green \nRori Green is a Geological Engineer with 25 years’ experience in rock mechanics and slope stability. Since 2011 she has worked primarily on rockfall hazards in response to the 2011 Christchurch and 2016 Kaikōura earthquakes. She is the lead author for the MBIE guidance document “Rockfall: Design considerations for passive protection structures”. Rori is an independent consultant. \nClick on the link below to register (link will be shared once you have registered):
