Advances in Earthquake Engineering post the 2011 Christchurch Earthquakes

Dr Gary Chapman

Talking Points

Dr Gary Chapman, a principal Geotechnical Engineer with Golder Associates, has been working closely with the Golder Associates’ Christchurch office since the 2011 earthquakes.

His presentation will outline some of the learnings that have come out of the disaster and the  work that has been carried out in the design of new buildings post the earthquake and  the rectification of buildings damaged but not totally destroyed by the earthquakes.

Discussion will include a summary of the guidelines prepared for the rectification of houses damaged, but not destroyed by the earthquake, and building authority approved means of rectification of damaged buildings.

A large number of ground improvement contractors and consultants are now active in the Christchurch market, including a ground improvement joint venture involving Golder Associates and a Canadian contractor.

Various ground improvement techniques will be discussed including the pros and cons of various seismic rectification methods together with the geotechnical techniques used to assess future earthquake induced liquefaction and lateral spreading risks.
