v5.0 [May 21, 2009]
Analysis Options
- Combination Analysis
- Sensitivity Analysis
-Persistence Analysis
Combination Analysis
- combination analysis (new analysis type)
- import complete dips file (all planes)
- consider single file, or two joint sets
- view joint intersections on stereonet
- view failed poles/intersections on stereonet
Sensitivity Analysis
- sensitivity analysis
- sensitivity analysis variables - nearly all input parameters can be selected for sensitivity analysis, including variables which are not available for probabilistic analysis (e.g. support capacities, external load magnitudes, bench width, slope length)
- sensitivity analysis of slope orientation - can automatically use same dip direction for slope and upper face
Joint Shear Strength
- barton-bandis strength model
- power curve strength model
- waviness angle
Probabilistic Analysis
- import statistical info from Dips .dwp file
- joint shear strength can be defined directly as a random variable, for any strength model
- water pressure can be defined as a random variable
- seismic load can be defined as a random variable
- Fisher distribution
- new definition for probability of failure (use total # of samples)
- reliability index (normal and lognormal) reported in info viewer
- gamma distribution
- persistence analysis (define persistence and wedge height as random variables)
- checkbox to automatically use same dip direction for slope and upper face
- plot remaining bench width (if bench width option is used)
- default sampling method changed from Monte Carlo to Latin Hypercube
- default number of samples changed from 1000 to 10000
- default sampling changed from random to pseudo-random
- new random number generation options
Wedge Calculation
- completely new analysis engine based on Goodman and Shi's block theory
- provides reliable results for a wide variety of modeling circumstances
- handles wedge cases which could not be previously analyzed
Wedge Size
- improved scale wedge dialog (checkboxes to select parameters)
- scale wedge parameters saved with file
- scale wedge works with probabilistic or combination analysis
- scale by slope length
- minimum wedge size
Import from Dips
- import all joint orientations from a Dips file for Combination analysis
- import Fisher joint set statistics from a Dips file
Tension Crack
- tension crack location:
- minimum safety factor
- maximize wedge size according to bench width
Stereonet View
- new display options for probabilistic (or combination) analysis:
- display all poles on stereonet
- display joint intersections
- highlight poles/intersections corresponding to wedge failure
User Interface
- sidebar wedge information panel
- customize data display in sidebar
- improved Info Viewer layout with customizable fonts, colours etc.
- HTML Info Viewer
- new mouse options for moving wedge etc
- undo / redo
- pan model in view
- new zoom shortcuts (F-keys), hold Shift to zoom all views
- customize number of decimal places for analysis output
Miscellaneous
- Project summary (in project settings)
- export 3D dxf
- improved printing with customizable header/footer title blocks
- entire Wedge View is now printed (top / front / side / perspective), rather than just a single view
- duplicate current file (for any wedge generated by probabilistic or combination analysis)
- back compatibility with Swedge 4.0 (read / write files in version 4 format)
- customizable display options for chart properties
- changes to default slope display (actual slope height is used, new default colours)
- actual slope length and bench width can be displayed
- sampling option (probabilistic) moved from Input Data to Project Settings dialog
Documentation
- completely revised and improved help system (webhelp)
- new tutorials
- new theory manual
