We are pleased to announce two new geotechnical modules as part of the Earthquake Geotechnical Engineering Practice series. This is a joint MBIE and NZGS document and has been published as Building Act section 175 guidance.
The two new modules are:
- Module 5: Ground improvement of soils prone to liquefaction
- Module 6: Earthquake-resistant retaining wall design
These versions are being issued for public comment. Geotechnical, civil and structural engineers are encouraged to make use of these documents and return comments to firstname.lastname@example.org within six months for consideration by the editorial committee. Comments are also welcome from others working in earthquake engineering.
See all the modules here.
This module covers the design of ground improvement and supports the Canterbury Earthquakes Royal Commission recommendations to prepare national guidelines specifying design procedures for ground improvement, so as to provide more uniformity in approach and outcomes.
This module covers the seismic design of retaining walls of a routine nature throughout New Zealand and should be used in conjunction with established handbooks that cover other aspects of retaining wall design in all situations and soil conditions. It builds on and generalises the supplementary retaining wall guidance issued by MBIE supporting the Canterbury rebuild seismic design of retaining structures for residential sites in Greater Christchurch with accompanying worked examples.
