Dear folks,
One customer of mine is seeking to create a multiple pavement subassembly (PKT), but we are facing to a lack of knowledge about maximum slope and superelevation definition.
Here in the first (and simplified) case below, we tried to fix maximum slope at 4% for the L6 link. A input parameter “PENTE” is reaching the L1.slope. If this input value is superior at 4%, the L6 link must stay at 4% (we suppose the L5 depth is enough to fill material on site). Degree’s liberties are available with offset and elevation targets on P2.
We tried to implement a decision following two approches:
- With math.abs(PENTE)>4% formula,
- With generic definition of slope (∆y/∆x) comparing to CType(Pente,double).
Nothing is functioning. We thought to use a math.max(double1,double2) comparison but not allowed with VB Casting Expression. Forcing values with variables do not affect also.
I have a lack of idea now. Any thoughts?
We must take in consideration the superelevation calculation also.
Please find enclosed a quick draft of PKT with math.abs(PENTE)>4% formula.
Thanks a lot!
Best regards,
Q.
