摘要
在较为详细地讨论了卵型曲线的几何要素和中桩坐标计算的同时也介绍了不完整回旋线的计算方法，并附编写程序的框图供参考。该方法适用于大比例地形图纸上定线、优化设计和立交线形设计，由程序计算中桩坐标可为施工放样提供方便，提高放样精度。
The calculation of part easement curve is introduced after a detailed discussion on the calculation of geometric elements and station coordinates for oval curve in this paper; An attached flowchart is also supplied for reference. This method can be applied to paper location in the large scalemap、optimum design as well as the alignment design for interchange. In addition, station coordinates calculated in computer can also contribute to the convenience and accuracy of construction location.
