When the 2010 and 2011 earthquakes created a city-wide outdoor research laboratory, UC Civil Engineering Professor Misko Cubrinovski gathered as much information as possible. This work has been recognised by the American Society of Civil Engineers (ASCE), which is presenting him with the 2019 Ralph B. Peck Award for "outstanding contributions to the geotechnical engineering profession through the publication of several insightful field case histories"

Rick Wentz is a Chartered geotechnical engineer originally from Northern California who has lived in New Zealand since 2011 - coming here in response to the Christchurch earthquakes. Rick talks to Mark about seismic risk - what it means for the general community and the role of a geotechnical engineering in helping to manage it.

Twelve years after the CTV building collapsed during the Christchurch earthquake, families of the victims killed inside have told an engineering disciplinary hearing they want justice and accountability. 115 people died when the six-storey building came down in February 2011. A complaint against an engineer whose firm designed the building is being heard by an Engineering New Zealand disciplinary committee. Dr Alan Reay lost a High Court bid to stop the hearing. Anna Sargent reports.

Recent earthquakes have shown that liquefaction and associated ground deformations are major geotechnical hazards to civil engineering infrastructures, such as pipelines. In particular, sewer pipes have been damaged in many areas in Christchurch as a result of liquefaction-induced lateral spreading near waterways and ground oscillation induced by seismic shaking. In this paper, the addition of a flexible AM liner as a potential countermeasure to increase sewer pipe capacity was investigated. Physical testing through 4-point loading test was undertaken to characterise material properties and the response of both unlined pipe and its lined counterpart. Next, numerical models were created using SAP2000 and ABAQUS to analyse buried pipeline response to transverse permanent ground displacement and to quantify, over a range of pipe segment lengths and soil parameters, the effectiveness of the AM liner in increasing displacement capacity. The numerical results suggest that the addition of the AM liner increases the deformation capacity of the unlined sewer pipe by as much as 50 times. The results confirmed that AM liner is an effective countermeasure for sewer pipes in liquefied ground not only in terms of increased deformation capacity but also the fact that AM-Liner can prevent influx of sand and water through broken pipes, making sewer pipes with liner remaining serviceable even under severe liquefaction condition.
