option
in the Surfaces menu. Any number
of specific non-circular slip surfaces can be added to a model.Slide Model > Slip Surfaces > Non-Circular Surfaces
When the Surface Type in the Surface Options dialog is Non-Circular, the user can define:
Specific non-circular slip surfaces, and / or
Define a Block Search or a Path Search, to attempt to find the slip surface with the overall minimum safety factor for a given slope.
Specific Non-Circular Slip Surfaces
Specific non-circular slip surfaces are added to a model with the Add Surface option
in the Surfaces menu. Any number
of specific non-circular slip surfaces can be added to a model.
Non-Circular Surface Search Methods
There are two different NON-CIRCULAR Search Methods available in SLIDE, for locating critical NON-CIRCULAR slip surfaces - the Block Search and the Path Search. See the Block Search and the Path Search topics, for complete descriptions of these Search Methods.
NOTE:
For a given analysis, only ONE Search Method can be used, you cannot run both Search Methods at the same time.
However, specific non-circular surfaces AND a critical surface search can be defined and analyzed for the same model, this does not cause any problems.
Surface Optimization
A supplementary optimization can be applied to slip surfaces, after the initial analysis, in order to locate slip surfaces with an even lower factor of safety. See the Optimize Surfaces topic for details.
