Waste Rock Back Analysis

In This Issue

On October 4, 2004, during field measurements collected in trench LFG-008, a crack developed in the middle of the trench. This occurred during the destruction of the Goat Hill North (GHN) rock pile at the Questa site.

The slope had been pushed in a convex arc out from the original slope of the mountain in order to ultimately flatten the slope of the GHN pile and reduce a slope failure risk. Trenches were excavated through undisturbed zones of the original rock pile during the slope destruction process in order to provide insitu field testing / sampling opportunities for the Questa Waste Rock Pile Weathering Study. The crack formed an arc through the excavated trenches in a manner opposite to the lip of the slope.

The purpose of the back analysis was to identify possible soil strata/soil property scenarios that would produce a slip surface and failure condition at the location measured in the field.

Peter Brett Associates have been looking to update our existing slope stability software over the last year. After extensive research and trials, SVSlope developed by SoilVision Systems Ltd, was found to meet all our existing and future design requirements. Its ease of use for modelling simple as well as complex geological and geometrical problems was a critical factor in our assessment as well as the incorporation of design to the Eurocodes. Their customer support has been faultless and their willingness to develop the software to meet our own specific design requirements is a most gratifying added bonus.

We love the fact that SVSlope is part of an integrated suite of software and that, if required, 3D analysis can be undertaken. We would recommend this product to other geotechnical consulting firms.

Unsaturated Soil Mechanics in Engineering Practice

The definitive guide to unsaturated soil - from the world's experts on the subject!

This book builds upon and substantially updates Fredlund and Rahardjo's publication, Soil Mechanics for Unsaturated Soils, the current standard in the field of unsaturated soils. It provides readers with more thorough coverage of the state of the art of unsaturated soil behavior and better reflects the manner in which practical unsaturated soil engineering problems are solved. Retaining the fundamental physics of unsaturated soil behavior presented in the earlier book, this new publication places greater emphasis on the importance of the "soil-water characteristic curve" in solving practical engineering problems, as well as the quantification of thermal and moisture boundary conditions based on the use of weather data.
