Unequal-tangent Vertical Curve Problem; Given the station for vertex of the two curves, V= 46+ 75 : elevation of 872.13 feet. The grade G1= +4% and G2 = -3%. The length of curve one, L1 = 800 ft., and curve two, L 2 = 500 feet. Find the following: • Slope or grade of the line V1V2 • External distance VM, as shown on the figure below. • Construct equations for both curves. • Stations and elevations of the high points for each curve • Elevations of the midpoints for each curve (on the curve) Elev = 872.13 * 3% G, +4% M PVT с PVC L2=500 ft L=800 ft L =1,300 Ft Unequal Tangent Curve
