Abstract

Terms geometrik road is one of the requirements in the making of road construction, where this is useful for providing comfort, security and a smooth user jalan.Salah one component in the planning structure geometrik road is curved arch that is on the transition curve is used to make the transition part of the straight path to the road that had curved fingers with a slope of a curve, or vice versa At the time the vehicle enters the curve, it is gradually getting centrifugal style (the style that encourages vehicle towards radial routes out of the way) starts from zero to maximum and back to zero at the time go right back. To minimize the centrifugal style, the design in the form of a curve there are three types of curve that can be used in the implementation of Full Circle, Spiral-Spiral Circle-, and Full Spiral (Spiral-Spiral). One of the curve so that the form of centrifugal style that can be reduced Spiral-form curve Spiral. Type curve match for this type of curve-curve where a sharp corner of the deflation that is used relative large, the geometry consists of two curved transition In the science of civil engineering always used the formula-the formula that is so, regardless of the occurrence. to calculate all sesuatunya practitioners of civil engineering only depend on the table-table construction. To know is the formula, the final task in this modeling analysis akan curve type Spiral-Spiral and the decline in geometric formulation. The purpose of writing this final duty is to know the modeling structure shaped road junction Spiral-Spiral and how the steps formulasinya decrease. With the only restriction on the structure menganilasa road junction in the field even. Based on this discussion of the results obtained in the following election and memodelkan type junction road, junction when the road was designed and appeared to be LC (long curved circle) is less than 25 meters should be used then the curve-type Spiral Spiral. When the shifting tangent of the spiral is obtained after the survey, obtained less than 15 cm then the curve is used tipa veer Full Circle. When the LC length> 25 meters and shifting tangent more than 15 cm then the curve that is used is the type of curve-Spiral Circle-Spiral. While these steps decrease the formulation of sketches so that the curve obtained from the formula of the parameters used are sketches veer-type Spiral Spiral longer need to be simplified so that the one obtained saja.Bagian Spiral Spiral is analyzed with the approach so that the geometry obtained the following formula: YC (ordinate point SC perpendicular to the tangent line, the distance perpendicular to the SC point in the curve), xc (dot SC Absis the tangent line, the distance to the point TS SC), p (shifting tangent of the spiral), k (absis from a PC on the tangent line spiral), TS (tangent length from the point PI to point to point TS or ST), Es (PI Distance bow to the circle)
