Abstract The New Zealand Geotechnical Society’s “Guideline for the field classification and description of soil and rock for engineering purposes” (NZGS, 2005) has for 13 years been the standard by which soil and rock logging has been undertaken in New Zealand. NZGS (2005) does not…
Abstract A routine part of any geotechnical investigation is the classification of the recovered soils. In New Zealand this should be undertaken in the field in accordance with the New Zealand Geotechnical Society’s guidelines. There is a general expectation that laboratory-based methods should both verify…
The design of piles is typically undertaken using empirical or semi-empirical methods developed for ‘regular’ silica sands or clays. The application of such methods to geological materials whose physical characteristics are unlike those on which the conventional design methods were derived can result in unconservative…
