Entry and Exit Search Method in SVSlope® 3D

A feature of SVSlope® 3D

July 4, 2011

Based on feedback from our beta testers, SoilVision Systems Ltd. has implemented an additional method of specifying a group of slip surfaces for a SVSlope® 3D analysis. The new method is an entry and exit search method, which is a 3D extension of the existing 2D entry and exit method already implemented in SVSlope® 2D.

The new method allows the user to define a plane which defines the center of the proposed slip surface. Next, by switching to a two-dimensional view of that vertical plane, the user can specify entry and exit points graphically on the screen in a manner very similar to the two-dimensional implementation. The end result is a methodology whereby entry and exit points for an elliptical slip surface can easily be specified in a 3D analysis.

The steps to use this feature are illustrated below. Begin by opening the Settings dialog found under Model > Settings and selecting the Entry and Exit search method:

Step 1: Specifying the Entry and Exit search method

Open the Entry and Exit dialog by selecting Draw > Entry and Exit from the menu. Click on the "2D View" button to select the coordinate of the centerline of the slip surface:

Step 2: Entering the entry and exit coordinates

Use the slider or the text box to select the desired coordinate of the centerline of the slip surface:

Step 3: Selecting the coordinate of the slip surface centerline

Return to the Entry and Exit dialog, then use each "Draw" button to draw the entry line and the exit line:

Step 4: Drawing the entry and exit lines

Once these steps are complete, analysis can begin!
