plot the given and show solution
A-3.3% grade meets a 8.2% grade at a vertex
(EI. 143.53m) directly under an overpass
bridge having underside elevation of
154.89m. A 6.4 meters clearance under the
bridge and the center of the curve was
observed. Determine the elevation at the
bottom of the invert when its location from
PC is 79.9m. The pipe has an outside
diameter of 1.0 meters and a thickness of
52.7mm. The backfill is 0.4 meters in depth.
The bridge is having a width of 17.6 meters.
