WebbHome » Surveying and Transportation Engineering » Simple Curves Problem 01 - Simple Curve Problem The angle of intersection of a circular curve is 45° 30' and its radius is 198.17 m. PC is at Sta. 0 + 700. Compute the right angle offset from Sta. 0 + 736.58 on the curve to tangent through PC. A. 2.98 m B. 3.37 m C. 3.09 m D. 3.87 m Solution WebbA simple curve in a highway is to be analyzed . The azimuth angle of its tangent lines are 1,102.7 degree and 836.6 degree respectively . Point A is located 181.55 meter distance from PC along the curve . The location of point A in the curve is known from the deflection line created by a 12.3 degrees deflection angle from PT .

A horizontal curve provides … WebbThe simple curve is an arc of a circle. It is the most commonly used. The radius of the circle determines the “sharpness” or “flatness” of the curve. The larger the radius, the …
WebbA simple curve is a single arc of a circle, which is tangential to both the straight lines of the route. There are a few elements of a simple circular curve discussed below. Back Tangent: The line of a tangent before the beginning of the curve is known as a back tangent. WebbIn arc definition, the degree of curve is the central angle angle subtended by one station of circular arc. This definition is used in highways. Using ratio and proportion, 1 s t a t i o n …
WebbSPIRAL CURVES A PRACTICAL SOLUTION Lynn Caswell, L.S. 12/27/08 Transition curves, also known as spiral curves, were used on Interstate Highways, County Roads and Railroads. Most of the public right of ways have been re-platted to eliminate the spirals on right of way but there still are a few to give the Land Surveyor a challenge. WebbThe azimuth of the tangents of the simple curve is 514 degrees and 759 degrees respectively. The radius of the curve is 213.2 meters. Station A is lying on the curve having a deflection angle of 8 degrees from PT. Determine the: Show Solution Distance of the middle ordinate of the simple curve in meters.
