Solved - Vertical parabolic curve - PVI, PVC and PVT and Elevations at different stations along Curve


Hi, 
Here is the example which shows you how to solve for the vertical transition curve elevation.


Problem: A 3% grade intersects a -2% grade at station 4+350m with an elevation of 190.5m. Given that a 250m symmetrical parabolic curve highway is utilized, determine:
elevation in meters at station 4+240
elevation in meters at station 4+260
elevation in meters at station 4+280
elevation in meters at station 4+300
Vertical Parabolic curve - PVI, PVC and PVT

Solution: Please refer the images below.
Parabolic vertical curve - elevation at stations along curve


thanks!
