ABSTRACT The Magnitude (Mw) 7.8 Kaikōura earthquake struck the east coast of the South Island of New Zealand in November 2016, resulting in widespread damage to the slopes along the Kaikōura coast. Many of the subsequent remediation measures relied on rock anchors, and a significant…
ABSTRACT Sumner Road between Lyttelton to Evans Pass was severely affected by rockfall as a result of the 2010-2011 Canterbury Earthquake Sequence. Approximately 2 km of Sumner Road was closed to all traffic following the 22 February 2011 earthquake. Sumner Road was used as a…
ABSTRACT Rock slopes in most mining areas are prone to instability, because of the rock mass conditions are strongly effected by both internal rock properties and external conditions. Therefore, instability of rock slope attracts a high level importance for researchers, especially in the conventional…
Abstract Disaster recovery takes place in an abnormal environment. A defining tension exists between the need to rebuild quickly, but with careful deliberation. This tension poses risks for the health and safety of workers involved, at a time when risk levels are higher than normally…
Abstract This paper outlines key elements and the main findings for seismic design of geotechnical structures, i.e. earth retaining systems as well as natural and man-made slopes, and provides an unabridged roadmap for a streamlined design following the principles of value engineering and performance based…
This paper was previously submitted to NZSEE 2018 and published as a poster ABSTRACT Following the M7.8 Kaikōura Earthquake in New Zealand, Hiway Geostabilization (HGS) was awarded the North Face Ohau Point Scaling and High Tensile Mesh Installation contract. The original design to mitigate rockfall…
This paper presents a simplified procedure for predicting earthquake-induced level and sloped ground failure, namely liquefaction and shear failure. It consists of a framework where cyclic stress ratio (CSR), static stress ratio (SSR) and undrained shear strength (USS) are formulated considering simple shear conditions, which…
Surface and borehole seismic imaging with both P and S waves enhance site assessments and reduce risks at difficult and complex geotechnical sites. These technologies increase the effective radius of investigation of boreholes alone and provide improved site parameters such as dynamic elastic modulus. Case…
