Typical section rules
A rule is written once; at each station the program decides whether it will be a slope, a wall or a ditch.
3rules
4 mwall threshold in fill
7.5 mmaximum wall height
1:3safety slope in low fill
What the program did
- Used a wall instead of a slope at stations where the fill height exceeds 4 m.
- Applied a flatter 1:3 safety slope in fill lower than 2 m.
- Added a 0.5 × 0.5 m ditch at the toe of the slope in cut.
- Showed in the preview which rule the section switches to as the ground changes with the trial slider.
What the engineer approved
- Wrote the three rules and their threshold values.
- Tested the result at different ground heights with the trial slider.
