Version 3.014
| 1. |
Export
image now works on Vista. |
Version 3.013
| 1. |
Added warning when
ratio of the excavation coordinates to the excavation
dimensions is too large. Warning appears after
adding an excavation
boundary either manually or from a DXF. |
| 2. |
Apex angle
is now computed correctly according to the description
in the help. It use to be the minimum of the angles
between the 3 wedge edges, now it's the minumum
internal angle between an edge and the opposite
face. |
Version 3.012
| 1. |
Swellex and Split-Set
bolts now allow entry of a plate capacity. |
| 2. |
Help Update. |
Version 3.011
| 1. |
If a bolt excavation
end point lay directly on an excavation vertex,
then in some cases
the
bolt would not be included in the analysis. |
| 2. |
Improved documentation
for shorcrete shear strength and failure modes. |
| 3. |
Lowered
the default shotcrete shear strength to be more
in line with Canadian codes for unreinforced concrete
shear strength. |
Version 3.010
| 1. |
New help
system including new tutorials. |
Version 3.009
| 1. |
If a horizontal
plane intersects a horizontal tunnel at the first
vertex, and was first in the plane order, negative
values of volume and incorrect modes of failure
would result. |
Version 3.008
| 1. |
Now supports
multiple HASPHL locks on the same USB hub |
Version 3.007
| 1. |
The units for support
pressure were displayed incorrectly as force units
instead of the correct pressure units in both the
infoviewer and the sidebar. Fixed. |
| 2. |
New Hasp-HL
hardlock support. Removed support for old beige
hardlocks. |
Version 3.006
| 1. |
Speed Improvements
for the combination analyzer. Can now handle larger
numbers of joint combinations. Hint: Turn of the
calculation of end wedges in the project settings
if you are not interested in end wedges. This greatly
improves speed as well. |
Version 3.005
| 1. |
If one of the joint
planes making up a wedge was orthogonal to the
plane of sliding, in shuch a way that there was
no normal force on the plane but the wedge slides
along the plane, cohesion on the plane was not
being factored into the factor of safety. This
resulted in factors of safety less than the true
factor of safety. This is a rare case. |
| 2. |
Dxf files with arcs
using negative bulge factors would not be imported
correctly. |
| 3. |
Can now pan the perspective
view. |
| 4. |
Some very
old files (from Unwedge for DOS version 1.x) would
not
load properly (the unit system was not set properly,
after the file load). Fixed. |
Version 3.004
| 1. |
When calculating safety
factors using stress analysis results, the program
would overestimate the safety factor. The reason
for this is in the fundamental formulation used
that included shear stress as a driving force.
This is wrong and has been removed. The program
now closely matches Phase2 and UDEC numerical
analysis results when looking at prismatic wedges
(soon
to be released!). It also matches analytical results
presented in Brady and Brown "Rock Mecanics for
Underground Mining" and papers published. |
| 2. |
It was possible for
bolts to unload a sliding plane to a point where
contact was lost. This would result in a reduction
in safety factor if cohesion on the sliding joint
was used. The program has been updated so that
contact is never lost, so cohesion always exists.
As a result, increasing the bond strength or capacity
will not result in a reduction in safety factor
for this case. |
| 3. |
Input data dialog
restricted plunge to [0,90]. The allowable range
is now
[-180,180] which is the same as the side bar. |
| 4. |
Tunnel axis (optimization)
plots would sometimes be blank for the "factor
of safety" plot if the "Wedges to Analyze" in
the Tunnel Axis Plot Settings
was changed to a single wedge. |
| 5. |
When using stress
with joints that have different properties, the
program might use the wrong set of properties on
a joint plane. |
| 6. |
On Windows XP, the
scroll bars did work correctly for the list of
possible variables, in the tunnel axis plot's "define
user data equation" dialog. |
| 7. |
The Barton-Bandis
strength criterion has been updated to include
the 70 degree maximum at low confining stresses
(Barton and Choubey 1976). Phib has also been changed
to Phir to better represent the current criterion.
The help has been updated as well. |
Version 3.003
| 1. |
The combination
analyzer for support pressure was broken in version
3.002. |
Version 3.002
| 1. |
For sliding wedges
with stress, the weight was not being included
in the driving force calculation. |
| 2. |
Support for new Educational
system. Also update dll's to latest microsoft versions. |
| 3. |
Fix - the
combination analyzer sometimes displayed values
for "Required Support Pressure" that
were too large. Only the values of "Required
Support Pressure" in the combination analyzer
dialog were affected. All other values in the dialog
were correct, and the rest of the program was not
affected. In all cases, the value that would be
reported would be greater than (more conservative)
or equal to the correct value. |
Version 3.001
| 1. |
Release of Windows version of Unwedge. |
