ABSTRACT
The general mechanisms of landslide related geohazards are now fairly well understood but there remains the problem of establishing the risks to structural design and construction. This is being tackled by relating the local ground conditions to the regional geological surveys and integrate this with site-specific information using a Geographical Information System. For regional scales of assessment, influence based upon statistical analysis has been successfully applied to reflect their degree of influence, and then the factors combined to produce a hazard potential. The main aim of this contribution is to highlight the need for a probabilistic framework for slope stability analysis and emphasize that at present stage, the deterministic and probabilistic approaches must be regarded as complementary.
