Slope Search
A Slope Search is one of the Search Methods available in Slide2 for locating the Global Minimum safety factor for CIRCULAR slip surfaces. In order to perform a Slope Search, the Surface Options dialog must be configured as follows:
- Surface Type = Circular
- Search Method = Slope Search
How Does the Slope Search Work?
The Slope Search method in Slide2 allows you to define the search by defining areas of the slope which will be used to generate slip circles. This is done with the Slope Limits option.
- The Slope Limits are used to randomly generate TWO points on the slope, which define the starting and ending points of the slip surface on the slope.
- In order to define a slip circle, THREE points are needed. The third point for each slip circle is generated using the Initial Angle at Toe.
The Slope Search method in Slide2 (for circular surfaces), is very similar to the Path Search method in Slide2 (for non-circular surfaces). In the Slope Search method, the surfaces which are generated are constrained to be circular, whereas in the Path Search the resulting surfaces are irregular and non-circular.
