The minimum data necessary is the degree of curve, central angle of the circular curve, length of spiral and spiral central angle. For 110 spirals, length = 1815.10 feet. which may come in handy in your surveying adventures. Spiral Curve Offsets. The remaining spiral stations are set by subtracting their deflection angles from 360 degrees and measuring 25 feet from the previously set station. The following computations are for a spiral when D, V, PI station, and I are known. To start with simply, choose a curve where everything is set equal to y, as above. The surface area of the archimedean spiral can only be calculated if the number of turnings is an integer. l Spiral arc from the TS to any point on the spiral l Ls at the SC. From table 1, when D = 4 and V = 60 mph, the value for Ls is 250 feet. We start with the central point and arrange the positive integers in a Spiral fashion (anticlockwise). This calculator calculates the deflection angle to any point on the curve (i) using length of spiral from tangent to any point (l), length of spiral (ls), radius of simple curve (r) values. D Degree of curve of the spiral at any point, based on a 100 foot arc English units only. C denotes circumference of spiral.

This places the PVI at sta 23+00 elev 852.75 ft. Radius Through Three Points. Determining Ls. While a circular curve has a radius that is constant, a spiral curve has a radius that varies along its length. The spiral curve is designed to provide for a gradual superelevation of the outer pavement edge of the road to counteract the centrifugal force of vehicles as they pass. The first curve of the section is the Hyperbola, y=c(x^2 - a^2)^.5, with 6 variations of a and c given.
Because there is a linear relation between radius and the angle, the distance between the windings is constant. It was the famous Leonhard Euler who investigated the curve as first (in 1744). 0. alavy110. Free Downloads: Spiral Curve Calculations. Horizontal Curve Calculator in Excel.
