special excavation and backfill.
Available Concrete Fill Wall Criteria Files:
Criteria File |
Elements Drawn by Criteria File |
c_cwal1d.x08 |
Cantilever concrete fill wall plus associated
excavation and backfill.
Uses lines in plan view dgn file to set station ranges and
offset. |
c_cwal1s.x08 |
Cantilever concrete fill wall plus associated
excavation and backfill.
Uses exceptions data file to set station ranges and side
of roadway. |
c_zwalld.x08 |
Cantilever concrete fill "zee" wall plus associated
excavation and backfill.
Uses lines in plan view dgn file to set station ranges and
offset. |
- Description:
- Draws a cantilever concrete fill wall plus associated
special excavation and backfill. Station ranges and offset
from the roadway centerline are set using line(s) drawn
in a plan view dgn file.
(Constrast this with c_cwal1s.x08, where the station ranges
and side of the roadway for the cut wall are set in the
exceptions data file.)

- "cantilever wall parapet height"
- "cantilever wall parapet thickness"

- "min footing depth" (see Misc.

variables that must be assigned values in the input data
file:
- "type 1 concrete wall in dgn"
Variables that must be defined in exceptions
data file:
Notes for c_cwal1d.x08:
- Both station ranges and offset from centerline for the
wall are set using lines drawn in plan view dgn file (define_dgn
variable "type 1 concrete wall in dgn").
- "type 1 concrete wall in dgn" line defines the offset
from roadway centerline to the inside face of the parapet
wall. The pavement structural section is widened as
necessary to position the wall to match the "in dgn" line.
- This criteria file is a generalized rewrite of the wall
criteria used for Generals Highway at Sequoia National Park.
- User specifies all the dimensions for each of nine different
wall sections ("cantilever wall ... [1-9]") in the input
file, with "wall 1" being the shortest progressing to "wall
9", the tallest. By default dimensions for all the wall
sections are set in the criteria file itself to the values
used for Generals Highway, with the tallest wall ("cantilever
wall height 9") being 5.50 meters.
- Height of wall selected by this criteria is the shortest
wall that satisfies both the "min footing depth" and the
"min footing setback" requirements. (See Misc.Details
section below for further explanation of these variables.)
- Wall will always be drawn where called for, even if the
entire wall is below existing ground -- in which case the
shortest wall height ("cantilever wall height 1") is used.
- If none of the specified walls satisfy the minimum footing
depth/setback requirements, then a vertical line is drawn
from top of pavement down to existing ground. This
will allow earthwork and construction reports to be run
on the cross-sections.
- User must specify level/symbology very precisely for
earthwork and the slope stake report.
- Earthwork

Notes for c_cwal1s.x08:
- Station ranges and side of road for the wall are set
using the _d_use_cantilever_wall1s_[lt,rt] variables in
the exceptions data file using the following syntax:
if sta >= 1+000 r 1 and sta <= 2+000 r 1 then
{
_d_use_cantilever_wall1s_lt = 1
}
- Wall is drawn at whatever point the preceding criteria
file left off drawing; no pavement widening is done by this
criteria.
- This criteria file is a generalized rewrite of the wall
criteria used for Generals Highway at Sequoia National Park.

- Description:
- Draws a cantilever concrete "zee" wall plus associated
special excavation and backfill. Station ranges and offset
from the roadway centerline are set using line(s) drawn
in a plan view dgn file.
User defines five wall heights and associated wall component
dimensions.

Notes for c_zwalld.x08:
- Both station ranges and offset from centerline for the
wall are set using lines drawn in plan view dgn file (define_dgn
variable "zee wall in dgn").
- "zee wall in dgn" line defines the offset from roadway
centerline to the inside face of the parapet wall.
The pavement structural section is widened as necessary
to position the wall to match the "in dgn" line. (The width
of the concrete cantilever is fixed.)
- This criteria file is a generalized rewrite of a wall
criteria used for Generals Highway at Sequoia National Park
10(2).
- The height of the wall drawn by this criteria is selected
from among five user specified wall heights ("zee wall height
[1-5]") in the input file. For each wall height the user
also supplies dimensions for the other wall x-section elements.
Wall heights should be in increasing order (i.e., "zee wall
height 1" should be the shortest wall height and "zee wall
height 5" should be the tallest.
- Default (metric) dimensions for all the wall sections
are set in the criteria file itself to the match the values
used for Generals Highway (see the table below). If the
default dimensions are acceptable then the user does not
have to define values for these variables in the cross-section
input file.

- Height of wall selected by this criteria will be the
shortest of the user specified height that satisfies both
the "min footing depth" and the "min footing setback" requirements.
(See Misc.Details section
below for further explanation of these variables.)
- If none of the user specified wall heights ("zee wall
height 1" thru "zee wall height 5") satisfy the minimum
footing depth/setback requirements, then this criteria draws
a "non-standard" wall height to fit the existing ground.
The height of the wall for this case is determined by setting
the toe of the wall footing "min footing depth" below existing
ground. The other wall x-section dimensions for this case
are the same as for wall height 5.
- Wall will always be drawn where called for, even if the
entire structure is below existing ground -- in which case
the shortest wall height ("zee wall height 1") is used.
- The dimensions of the concrete wall cantilever section
and the parapet wall are fixed. (i.e., they remain the same
regardless of wall height)
- Hidden define variables "~max wall search dist"
(default = 20) and "~min pvmt widening" (default
= 0.01) are available to fine tune the performance of this
criteria.
- User must specify level/symbology very carefully for
the cross section reports to work correctly. (Notice that
it was necessary to have the criteria draw an "extra" line
with level/symbology lv=45 co=45 in order to get the reports
to work.)
