Anchors


VS_32 Case2

This particular model looks at the stability of a geosynthetic-reinforced embankment on soft soil.

The analysis methods used for studying this model is:
Bishop.

The search for the critical slip surface is fully specified and the critical surface shape is non-circular. The fully specified method allows the user to completely specify the geometry of the analyze slip surface. This method is particularly useful for a back analysis in which the location of the slip surface is well known. The surface is defined by defining the center coordinates and radius of the critical surface.

VS_39_Clay_NoRein_Circular

This problem examines the stability of the embankment when it consists of sand or an undrained clay fill. The objective of this example is to compute the required reinforcement force to yield a factor of safety of 1.35. In each case presented, the embankment was first modeled without reinforcement and the critical slip surfaces determined.

The analysis methods used for studying this model are:
Spencer, and
GLE (Interslice Force Function - Half-sine).

The search for the critical slip surface is grid and tangent and the slip surface shape is circular. The grid and tangent methodology is one of the more common methods of determining the critical circular slip surface. In this methodology the trial slip surfaces are specified by a grid of centers and a set of lines to which the circular slip surface must be tangent.

VS_47

This particular analysis involves a planar failure through a soil nailed wall.The factor of safety is calculated for the undrained, homogeneous slope. In this case, the slope is reinforced by two rows of nails.

The analysis methods used for studying this model is:
Janbu Simplified.

The search for the critical slip surface is a block search and the slip surface shape is non-circular.

The block search method allows specification of a slip involving a "block" of soil with two hinge points. Trial slip surfaces are generated by placing a grid of trial vertices at each hinge point. Currently this searching method is only implemented in a 2-D analysis. However a 3-D wedge specified slip surface is most similar to a 2-D block search. The number of trial slip surfaces can then be calculated as: # trials = Left grid centers x Right grid centers
