Surface Definition - Failure Surfaces & Others
Have you ever battled with circular failure surface definition using the traditional concept of an abstract point in space? And then tried to relate
that surface to the slope surface? The old way can be a thing of the past - GALENA has a better way!
Circular Failure Surface definition using circle centers can be a thing of the past with GALENA's unique approach of definition in terms of the
actual slope rather than an abstract point in space.
With GALENA you can define circular failure surfaces simply by defining their X coordinate intersection points with the slope surface together with
a nominal or desired radius and leave the hard work to GALENA.
GALENA can, of course, still use the more traditional definitions; you can even combine the more traditional definitions with those provided by
GALENA's innovative approach.
Definition of non-circular failure surfaces and of all other surfaces, profiles and slices can be either with GALENA's CAD-style mouse line-draw
function, by keyboard coordinate entry, or a combination of both - you can even create a non-circular failure surface from a circular failure surface in a few easy steps.
Coordinates for surfaces and profiles can also be pasted into GALENA from your spreadsheet program using standard cut & paste functions.
Definition made easy - the way it should be!
The image below shows a proposed tailings dam staged-augmentation project - the profiles with the yellow color band represent the tailings, and the
profiles with the gray color band represent the core material. Most of the profiles used in the augmentation study are defined by two or three points.
Should it prove possible to steepen the slope surface it would be a simple matter of re-defining or editing the slope surface only. To widen the
stage core would only require two points on seven profiles to be shifted to the right, much less work than a complete re-definition o f the model, including all profiles, as in most other programs.
