Moving Wedges in SVSlope® 3D

A feature of SVSlope® 3D

July 4, 2011

One of the important SVSlope® 3D beta tester requests was the implementation of moving wedges in an analysis. In previous versions of SVSlope, a single wedge could be entered and analyzed. A wedge in SVSlope 3D is similar to a block failure in SVSlope 2D. In SVSlope 2D, a variety of block trial slip surfaces can be analyzed by specifying grids of hinge points as shown here:

In a 3D analysis, a block failure becomes a failure wedge as shown below:

Based on feedback from our beta testers, our engineers designed a new moving wedge dialog which allows the input of multiple trial planes for each side of the wedge failure. Multiple variations can be analyzed by specifying a minimum, maximum and number of increments for each trial plane:
