Unwedge's Windows-based interface provides an easy to use, graphical environment for data entry and visualization that greatly simplifies the analysis and design process. Popup windows allow for easy entry and modification of model parameters, and easy to use editing tools provide a convenient method for performing parametric studies. The graphical data interpreter provides a rich set of tools, including 3D animation, for the convenient display of wedges surrounding the excavation.
In addition to allowing for simple point and click geometry input/editing, Unwedge provides enhanced support models for bolts, shotcrete and support pressures, the ability to optimize tunnel orientation and an option to look at different combinations of three joint sets based on a list of more than three joint sets. Unwedge uses a new analysis engine based on Goodman and Shi's block theory, which includes the ability to incorporate induced stress around the excavation and the effect on stability, new strength models such as Barton-Bandis and Power Curve, and the ability to improve the scaling and sizing of wedges.

Incorporate induced stress around an excavation and analyze its effect on stability using Unwedge’s new analysis engine based on Goodman and Shi’s block theory. Wedge computation is quicker and more accurate and the ability to scale and size wedges is improved. An entirely new calculation algorithm has also been added for finding and determining the size of possible end wedges.
0Unwedge provides new strength models such as Barton-Bandis and Power Curve. Choose from new bolt models including cable bolts, Swellex and splitset and enhanced support models for bolts, shotcrete and support pressures. Account for bolt orientation efficiency, bolt shear strength and joint waviness factor. Simulate multiple layers of shotcrete with different properties.
New features also include pseudo-static seismic load and a boundary element stress analysis option that allows users to determine how stress affects the stability of wedges. Scaling of wedges now more accurately reflects the values defined for trace length and persistence and Unwedge will also work to determine the maximum volume wedge with user defined trace lengths.
Editing support is easier than ever before. Unwedge 3.0 contains a new Integrated Stress Analysis module and the Tunnel Axis Plot shows how results change as tunnel orientation changes. The Joint Combination Analyzer will automatically analyze multiple combinations of three different joint sets. New clipboard support means users can easily create screen captures to illustrate their reports.
