Situația inițială

The Kaikoura M7.8 Earthquake caused widespread damage to the road and rail corridor over 20 km North and South of the Kaikoura township. Initially, over 40 major slips inundated the road and rail with over 750,000 m³ of material from source zones up to 500 metres above sea level. The loosened highly fractured Grey Wacke has caused frequent rockfalls, shallow landslides and debris loads generally in or after periods of heavy rainfall.

The hazard associated with the failures created a requirement to install shallow landslide barriers in several open slope locations to be able to maintain the SH1 road and Railway below. The major design constraint for the sites was minimising the deflection of the barrier in rockfall and debris load events.

Descriere

The 3.5m high SL-150 barrier was selected due to its 150kN/m² load capacity with low defection (< 2.2 metres in a debris load event) and due to it being the only certified and tested landslide barrier. To lower the deflection for the maximum energy level (MEL) rockfall event, a custom transmission rope was designed and installed. The lower deflection was required due to the close proximity to the railway.

To date, six SL-150s ranging from 24 metres to 126 metres long have been installed in the Kaikoura region with three of them having an additional transmission rope.
