GALENA incorporates three methods of slope stability analysis so you can assess a wide range of ground stability problems in both soils and rocks. With all three methods available in one package. You can tackle any problem in a variety of ways without stooping to load a new program.
-The BISHOP Simplified method determines the stability of circular failure surfaces.
-The SPENCER-WRIGHT method is used for either circular or non-circular failure surfaces.
-The SARMA methods is used for problems where non-vertical slices are required or for more complex stability problems..
Slop Stability Analysis
UNIQUE FEATURES
Back Analysis GELENA4S rapid back analysis 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 design of existing slopes. It answers the question of “what strength is required” rather than “what is the stability of the slope”.
Searching within known constraints
In the real world, engineering are only concerned with stability within certain limits. GALENA introduced the concept of “restraints allowing you to focus your investigation on realistic failure surfaces taking account of geological structure. Galena enables you to define the failure surface in terms of the actual slope rather than in terms of an abstracts point in space for greature accuracy.
Sophisticated Geological Modeling
GALENA enables you to define the soil or rock composition of particular problem independently of the structure or excavation being considered for fast assessment of design options. The slope surfaces are independent of the material profiles in terms of definition and can be moved without changing any of the material profiles.
Failure Criteria
GALENA offers mohr-Coulomb or Hoek-Brown failure criteria for assessing both soils and rocks.
Definiting Water Pressures & Other Forces
Ground water pressures, the most important parameter affecting the stability of structures and excavations, need to be defined realistically for different problems. GALENA enables water pressure to be defined as:
 A simple phreatic surface
 A piezometric pressure one or all layers
 An Ru pressure or all layers
 A dense above-ground liquid medium such as tailings slurry or
 Any combination of these
Galena also allows definition of tension cracks, surface point and distributed load, and earthquake forces. Tension cracks can be manually defined or can be specified for GALENA to aut matically generate them for all analyses on the run.
-GELANE is powerful.
-GALENA is engineer-friendly software.
-GALENA’s data structures are logical-definition of most options is available at the press of the button.
-GALENA‘s model files are designed for ‘what if’ scenarios with single option amendments for additional analyses.
-GALENA offers clear graphical images for a clear understanding of the situation being modelled.
-GALENA is menu driven program which makes it easy to use for first time operators.
Galena was developed by geotechnical engineers for practical use in the field
