SESOC Retaining Wall Design Guide - Methodology and Validation

Abstract

Some years in development, the SESOC Cantilever Timber Pole Retaining Wall Design Guide has been prepared in response to the need for a comprehensive, coherent design basis, albeit for low rise, cantilever, walls. Though based on long established Geotechnical principles, the nuances of incorporating the multiple facets in to a single, consistent and coherent whole has been, well, challenging. In addition to independent review by some key senior NZSEE members, it was recognised early on that robust, independent, validation would be crucial to ensure consistency of results and alignment with best practice. This paper will : a) Overview the basic principles, briefly, with more detailed coverage on : b) The verification plan, validation process, and the multiple approaches (and software solutions) employed.
