SR4 Assessment of slope stability at building sites (1987)

Most local authorities require a favourable report on the stability of sloping land before issuing a building permit. A variety of different approaches is used in making slope stability assessments ranging from superficial inspections to detailed investigations involving subsurface investigation, laboratory testing and stability analysis.

This report reviews the procedures commonly employed in slope stability assessments in New Zealand at present. The advantages and disadvantages of these procedures are discussed and, where appropriate, recommendations made as to their most suitable application.
