Material properties can also be defined for slice boundaries when using the Sarma method of analysis in GALENA, thereby allowing you to model discontinuities and/or joints that may have properties different to those of the surrounding materials. You can of course choose not to define material properties for slice boundaries and simply leave it to GALENA to automatically determine slice boundary properties from surrounding materials.
GALENA includes tables and Tools functions to assist with estimation of material properties for cohesive and non-cohesive soils, according to published data and information.
Tables and Tools functions are also included that enable you to determine RMR (Rock Mass Rating) from input parameters according to Bieniawski. Calculated or entered RMR values can also be used to calculate suggested strengths based on the works of various published authors.
