Tauroa residential subdivision

Landslide remediation and hill slope stabilisation for earthquake resistance

  • Riley C. Gerbrandt Opus International Consultants Limited, Wellington, New Zealand

Abstract

The Tauroa residential subdivision is situated in the hills of southern Havelock North in Hawke’s Bay, New Zealand. The development proposal includes removal of a moderately deep (<10 m) landslide and its replacement with an engineered fill slope. A simplified “screening analysis” method was utilised to develop reduced equivalent horizontal seismic loads for use in a pseudo-static slope stability assessment of the proposed remedial engineered fill slope. This risk-based method allows limited slope deformations to occur as a result of the design seismic event, with the magnitudes of the allowable slope deformations set in accordance with the tolerance level of the proposed development.
