Modeling Concrete Retaining Wall
Introduction:
There are several type of retaining and noise walls the
Geotechnical Unit can proposed. The Roadway Corridor Modeling aspect has
two benefits.
- The top and bottom wall envelope profiles can be used to design the
wall dimension.
- Visual inspection of the wall structure and location in proximity
of key area of concern before it is built.
Wall components are included in the Standard Template Library.
However it is not part of the pre-built standard template. The user has
to customized the roadway template to include the wall components into
their templates.
Objective:
Model proposed concrete retaining wall with SBG on the left
side from station 13+00 to 16+83.63.

NOTE: The content of the ZIP dataset
file must be extracted to the root C:\ directory.
Each chapter is then automatically expanded to the "C:\NCDOT
Training\Roadway\CM" folder. This folder structure
must be maintain to insure all saved ITL, DTM,
and RDP paths are set accordingly.

Exercise
Step 1.
While in the file b4657_rdy_cmd.dgn, launch
the Geopak Corridor Modeling tool.
Step 2.
Load the file b4657.rdp preference file.
Step 3.
Load the jobrdy.gpk file.
Step 4.
Launch Roadway Designer.
Step 5.
In Roadway Designer, load the
b4657.ird file.
Step 6.
In the Template Drops dialog box, verify
the template drops station ranges. Note the retaining wall is on
the left side from station 13+00 to 16+83.63. Close
out of the Template Drops dialog box.
Step 7.
In the Roadway Designer click on Process
All and Save the IRD.
Step 8.
Check the in the following settings in the Create Surface
dialog box. Apply and Close out of
the Create Surface dialog box. Close
out of Roadway Designer.

Step 9.
Verify the wall and SBG are displayed correctly in the 3D model
(DGN).
Step 10.
Close out of the file B4657_Rdy_cmd.dgn
and launch the file B4657_Rdy_XSC.dgn.
Step 11.
Open the Geopak Draw Cross Sections from Surfaces
dialog box. Enter the following settings for the XS Cells
tab.
