This paper presents the application software HYRCAN, which evaluates the factor of safety of circular failure surface in soil or rock slopes. HYRCAN offers a stand-alone windows system that is very simple to use, yet complex models can be created and analyzed quickly and easily. The graphical user interface enables quick generation of advanced models, and the enhanced output facilities provide a detailed presentation of computational results. The analysis procedures are fully automated and based on robust numerical procedures. Embedded scripting languages in HYRCAN enable the user to interact with and manipulate the models. This paper addresses the capabilities provided by pre- and post-processors for slope stability analysis and suggests enhancements and new features likely to be developed in the near future.
