A simple curve having a degree of curve equal to 5° is connected by two tangents having an azimuth of 230° and 280° respectively. It is required to replace this curve by introducing a transition curve 80 meters long at each end of a new central curve which is to be shifted at its midpoint away from the intersection of the tangents. (1) Determine the radius of the new central curve if the center of the old curve is retained. (2) Determine the distance by which the new curve is shifted away from the intersection of the tangents. (3) Compute the length of throw.

Step 1
Given that D = 5°, we can solve for R to find the radius of the old curve. R = 180°/πD = 180°/π*5° = 20.94395102393195 radians. Since the center of the old curve is retained, the radius of the new central curve will be the same, i.e., approximately 20.94 Show more…

Three simple curves are connected to each other such that the first and second curves form a compound curve while the second and the third form a reverse curve. The distance between the point of curvature and the point of tangency of the compound curve, which is also the point of reversed curvature of the reversed curve, is 485.025 meters. If the angle of convergence between the second and third tangents is 15°, I1 = 45°, R1 = 190.986 m, I2 = 60°, R3 = 159.155 m, and the stationing at PC is 0+520. Determine the angle between the long chord of the compound curve and the second tangent.
