| 摘 要： | 在市政工程(电信、电力、上下水、热力等线性工程)、道路公路设计和测量定线中经常遇到这样一类问题,即当带有回旋曲线的道路中线一经确定,其路边线、辅路、匝道和其他市政配套管线要求与主路中线平行布设,这样就提出了回旋曲线如何平移最为合理的问题。此文就以对称基本型回旋曲线为例,对这一课题的几种计算方法进行初步的探讨,以供参考。

| Abstract: | Once road centerlines with circular curves are decided,roadside lines,bypass roads,circuits or other municipal pipelines will be laid and should be paralleled with the centerlines.This case is frequent in public works(telecommunications,electric power and other linear engineering),Highway road design and alignment measurement.The problem that how to translate the circular curve is most reasonable is proposed.In this paper,based on the basic symmetric circular curve,several calculation methods are discussed. |
