Another of the unique features available only within GALENA is BackAnalysis, a feature recently commented on by some of our users:
"...that marvelous BackAnalysis feature...," "...this BackAnalysis is magic...," "...BackAnalysis really gives us a full appreciation of the situations we are modeling...," "...BackAnalysis in 3.1 is going
to save us so much time..." and "...thank you for making BackAnalysis better and easier in version 3.1."
GALENA's rapid BackAnalysis function takes the trial and error out of determining ground support requirements. It can be used for both back analysis
of past failures and for the design of existing slopes. It answers the question of "What strength is required"? rather than "What is the stability of the slope"?
BackAnalyses can be undertaken on any model using any of the methods of analysis available in GALENA - you can specify a single or multiple
BackAnalysis. For a single BackAnalysis, you define one Factor of Safety; for a multiple BackAnalysis, you define up to ten different Factors of Safety - a curve will be calculated and displayed for each Factor of Safety
defined. It's that easy!
BackAnalysis can also be used for Sensitivity Analysis to help answer the additional question of "How can we be sure that the material properties we
have used are truly representative of the slope"? With GALENA's rapid BackAnalysis function, you can see at a glance the likely range of material properties for a given Factor of Safety range.
The image below shows the results of a Multiple BackAnalysis - each curve is individually labeled with its relevant Factor of Safety.
