Slope stability analysis has for some years been regarded as an area where computing techniques can readily assist the engineer. The computer enables hundreds of potential slip surfaces to be analysed in a very short space of time and can subsequently search for the minimum factor of safety —all at very reasonable cost. Unfortunately the ease with which data can be fed in to commercially available programs with the satisfaction of almost immediate solutions being churned out has led in certain cases to the engineer no longer appreciating the significance of the analysis being undertaken.
