Slope
Limits OBJECTIVEIn this lab, GEOPAK will calculate
spot elevations at important changes in slope (locations of ground stakes)
for every station. The elevations and limits of construction lines will be
loaded into your road2.dgn. STEPSCopy lab9.dgn file
based on the class seed file (sur4201seed.dgn). Also place the job1.gpk,
criteria.inp (from lab 9) and road2.dgn (from lab
4) files in the same folder. § Open lab9.dgn you have copied §
Applications à § A dialog box like the one below pulls up.
§ Put in the right job number and chain name. § Select the Existing Ground Line image and put in the correct level symbology. § Select the Proposed Finish Line image and put in the right level symbology. § Select the Parameters button and choose the colors you will use for cut, fill and transition stations. § Hit Apply.
The results will be seen over the plan portion of your drawing (in
road2.dgn). Quite a bit of information has been added to your
baseline. Limits of construction lines
were plotted (where existing ground meets cut/fill). These lines are cut and fill lines. In
between cut and fill stations are transition lines. Spot elevations are labeled at key points
along the section. When finished, close
MicroStation and backup your files (lab9.dgn, job1.gpk) Earthwork OBJECTIVEIn this lab, GEOPAK will
determine earthwork values for the entire project. After you download and customize the earth.inp
file, it will be processed to calculate cut and fill areas and volumes per
station. This data will be summarized
in a file called earth.txt. STEPSIn this lab, we will be working
on the lab9.dgn file.
Since this lab will overwrite on the file, make sure to save a copy of
lab9.dgn some place else.
Open your lab9.dgn file and make sure the job1.gpk
file is in the same folder Download and customize the earth.inp template as you did with
the criteria and slope input files. Once your earth.inp
is customized, you can load it into the DGN by processing it. §
Applications à § Hit the Files button to select your earth.inp file § Change the Log File option from Screen Only to Log file, and name the out put file as earth.log (The log file will contain a summary of the input file processing and will be used to check for errors.) § Check uncheck the Pause on each section option to make the Apply button active. § Hit Apply § Hit OK for any errors prompted. § Exit § Use the navigator window as used in lab9 to navigate along your cross sections. Check earth.log
file for errors. If processing was
successful a summary of cut/fill areas and volumes will appear for each
station. The results will be seen over
the cross section portion of your drawing.
Cut and fill areas were filled in with white & blue respectively. The earth input file also created a second
file in your directory called 'earth.txt'. This file has the same information as the earth.log
formatted in columns. When finished, close
MicroStation and backup your files (lab9.dgn, job1.gpk, earth.inp,
earth.log, earth.txt)
