Line element method single intersection circular curve calculation program

The line element method single intersection circular curve calculation program is a small and practical circular curve edge pile calculation software, suitable for calculation of any curve such as transition curve, circular curve, straight line, S-curve, etc. Before using this program, you need to calculate the main point piles first. number and tangent azimuth, and then calculate the coordinates and azimuth of any point between each line element based on the line element method. This program is suitable for general types of curves, but is not suitable for compound curves, oval curves or non-complete transition curves.

Instructions for use

1. This software can calculate the center and edge pile coordinates and tangent azimuth of circular curves with transition curves. If you only need to calculate circular curves, enter 0 for the transition curve.​

2. Equipped with forward calculation and inverse calculation functions. Forward calculation: calculates coordinates through mileage and offset, and inverse calculation: reverses mileage and offset through coordinates.​

3. Data input: The curve rotation angle α and the calculated azimuth angle F are input in d.ms format. For example: -14°18ˊ10″ is: -14.1810. When "continuous calculation" is selected, the offset and declination angle are the same as the single point calculation.

4. It has data import and export functions. Known data can be input into a text document for import. Export is to export the entered data to a specified location.​

5. After the data processing is completed, click "Save Data" to save the five major curve piles and the curve parameter table. In the continuous calculation mode, "Save Data" can export the calculation results.​
