Quakes Royal Commission Releases Soils Report
The Canterbury Earthquakes Royal Commission has published another technical
report on its website and will hold a public hearing about the report at St
Teresa Hall in Riccarton, Christchurch commencing Tuesday 25 October 2011.
The report ‘Foundations on
Deep Alluvial Soils’ by University of Canterbury Associate Professor
Misko Cubrinovski and Ian McCahon of Geotech Consulting in Christchurch
is relevant to a number of aspects of the Commission's inquiry including
seismicity, the issues relating to the performance of buildings in the
Christchurch CBD and new technologies.
The report discusses the nature of the soils in the Christchurch CBD, and
their susceptibility to liquefaction. It describes the effect of
liquefaction in the Canterbury earthquakes on CBD buildings of different
foundation types, identifies foundation types and land improvement
measures suitable for buildings on deep alluvial soils, and discusses the
importance of appropriate field investigations and the need for a holistic
design approach that takes into account soil conditions, and foundation and
Professor Jonathan Bray of the University of California at Berkeley is peer
reviewing the report to ensure that advice given to the Commission reflects
international understandings and best practice.
The Commission has requested that any evidence or submissions on the
issues discussed in the report be provided in electronic form by Friday 7
October 2011. The evidence and submissions will be published on the
Commission’s website unless there are compelling reasons not to do so.
