Vertical Alignment (Menu - Build)

1. Configurations

This dialog is to edit the configuration of climbing Lane, ground level and layer.

1.1 Climbing Lane

- Entering Speed : speed of entering a car into climbing lane.

- Max-Climbing Speed : the maximum vehicle speed in climbing lane.

- Beginning-Speed of Full-Width : vehicle speed at the beginning point of full width in climbing lane

- Full-Width Lane : except taper, width of climbing lane.

- Ratio of Entering Taper : full-width over length of entering taper

- Ratio of Ending Taper : full-width over length of ending taper.

- Minimum Full-Width Length : length of climbing lane, except tapers.

1.2  GL/Layer

- Only STAs (By TIN) : if you want to get only one ground level on station, check it. But if getting the inflection points between stations, do not check it.

Only STAs is checked

Only STAs is not checked

- Depth of Ripping : depth of cutting rocks by dozer ripper.

- Depth of Soft Rock : depth of blasting rock which is softer than hard rock.

- Depth of Hard Rock : depth of blasting rock which is  harder than soft rock.

- Type of input[Layer] : if you select “Center Base”, you edit the elevations in the layer dialog, which are depths from ground level. If Selecting “Absolute Elevation”, you edit the elevations, which are elevations.

2. Build All

 Calculate ground elevations, layers, design levels and climbing lane,

3. Build GL

 Calculate ground elevations.

4. Build Layer

 Calculate layers.

5. Build DL

 Calculate design levels.

6. Build Climbing Lane

 calculate climbing lane.

7. Check Alignment.

If vertical alignment inputs have errors by specification., show them.

8. Clean

 Delete the results by command ‘Build All’ , ‘Build GL’, ‘Build Layer’, ‘Build DL’ and  ‘Build Climbing Lane’ .

9. View

9.1 PVI

 show the report of PVI (point of vertical intersection).

9.2 DL & GL

 show the result of ground levels and design levels by command ‘Build GL’ and  ‘Build DL’.

- STA : station

- Distance : cumulative distance(chainage)

- GL : ground level

- DL : design level

- DL-GL : design level minus ground level

- e :  gap between  PVI elevation and design level.

- slope : slope of station.

- x, y : x -coordinate, y-coordinate

- azimuth : azimuth of station

- index

        BP : Beginning Point

        EP : Ending Point

        BTC : Beginning of Transition Curve (Spiral Curve)

        ETC : Ending of Transition Curve (Spiral Curve)

        BC : Beginning  of simple Curve
