EXAMPLE PROBLEMS FOR TESTING SOIL SLOPE STABILITY PROGRAMS

In 1988 a set of 5 basic slope stability problems, together with 5 variants, was distributed both to the Australian geomechanics profession and overseas as part of a survey sponsored by association for computer aided design (acads). The problems were designed to test the abilities of programs in current use to handle the full range of situations likely to be met in daily practice, including complex soil profiles and slope geometries, pore water pressures, seismic effects, earth and rock dams, surcharges and non circular failure surfaces. It was therefore decided to prepare a detailed document for mailing to all known interested persons and organisations. The final document, comprising 47 pages, was mailed or handed to 120 recipients. The results for safety factor and failure surface cover a surprisingly wide range, with the means sometimes agreeing with the referee values and sometimes differing from them by more than acceptable amounts. The complete report of this survey can be found in report u255, by donald and giam (1989), published by acads. However, from this survey, the inescapable overall conclusion was that the local state of the art is not as good as it could or should be, especially for problems with complex details or requiring non circular failure surfaces.
