HP 32S-II Vertical Curve Program



#4

I new a guy from many years ago who wrote a program to solve for the elevation on a vertical curve, given station, elevation at BVC. Grade in and grade out, if you enter station to solve for, the elevation would be given. I forgot his name (its been 15 years and I live in a different state now) Does anyone have a program that they have written?


#5

If you know the horizontal length of the curve:


LBL E
INPUT I
INPUT G
INPUT H
INPUT X
*
+
INPUT H
RCL- G
2
/
INPUT L
/
RCL X
x^2
*
+
RTN

Where:
LBL E for elevation
I = initial elevation (BVC)
G = grade in as a decimal
X = location of the station
H = grade out as a decimal
L = total horizontal length of the vertical curve


Hope this helps, Eddie.


#6

  • Why do we have to INPUT H twice?
  • Did you ever run that program?
  • I think the correct formula to use is:
    E= I + G•X + H•(L - X)

Kind regards

Thomas
