Slope stability analyses have been performed using various software packages on a routine basis in geotechnical engineering since the 1980s. A variety of 2D software packages have been developed at the academic level and the commercial level to provide a comprehensive analysis of slopes. Many of these packages are now used by geotechnical consultants, often with little regard for the potential differences between the various analysis methods implemented in different software packages. Many of the early software packages do not appear to have been tested against a significant number of comprehensive benchmark examples. Recent studies have resulted in the collection of an extensive library of benchmark problems to which slope stability software packages can be referenced. In most of these situations a “correct” solution can be presented which provides a “reference benchmark” for testing slope stability software packages. The variation is typically not quantified. This paper summarizes the results of an extensive comparison of benchmark results obtained during the development of the SVSLOPE-3D software package. Issues surrounding the correct solution of benchmarks are discussed. The potential applications of this technology will also be discussed.
