Vertical curve solver
How do you calculate a rate of vertical curvature?
G1 = 1% G2 = -1% Calculated 2 a Rate of vertical curvature, K, is the length of curve per percent algebraic difference in intersecting grades (A).K = L/A a Rate of vertical curvature, K, is the length of curve per percent algebraic difference in intersecting grades (A).K = L/A
What is a vertical curve?
Vertical curves are used at changes of grade other than at the top or bottom of a hill; for example, an uphill grade that intersects an even steeper uphill grade will be eased by a vertical curve. The six possible combinations of plus and minus grades, together with sample computations of G, are shown in Figure 3-16.

General Equation of a Vertical PbliCParabolic Curve • For a second order parabola:For a second order parabola: Y =a+bX +cX2 p= a + p p • What is the physical meaning of: a, b, c? Define: Definitions –BVC = VPC V= VPI EVC = VPT –Percent grades g1, g2, r = rate of change of grade = (g 2-g 1 )/ L
How do you calculate the elevation of a BVC curve?
•Derivinggg g the general formula gives: •XX = g 1l/(g 1-g 2 ) = -g 1 /r where: X is the distance in stations from BVC to the high or low point. •Substitute in the tangent offset equation to get the elevation of that point. •El25Example 25-4 t th t ti d l ti f th4: compute the station and elevation of the highest point on the curve in example 25-1
