Elevation of a Point on the Curve Calculator

Posted by Dinesh on

Online civil calculator helps you to calculate elevation of a point on the curve. The vertical alignment of a transportation facility consists of tangent grades (straight lines in the vertical plane) and vertical curves.

Elevation of a Point on the Curve Calculation

Formula:

y = y0 + g1x + [(rx2) / 2]

where,
y0 - elevation of the beginning of the vertical curve (BVC)
g1 - grade just prior to the curve
x - horizontal distance from the BVC to the point on the curve
r - rate of change of grade
y - elevation of a point on the curve
