摘要
在公路、铁路、桥梁等工程中,缓和曲线应用较多。用全站仪或RTK放样时,有大量的坐标需要编程计算。但在现代线路设计中,由于应用了较多复杂的缓和曲线,传统的坐标计算方法变得困难。结合实际情况,分析不同缓和曲线的特点,提出对每一段线元,一律基于起始切点建立坐标系,计算坐标,统一计算方法。
Spiral curves are applied frequently to the project of highway, railroad, bridge, and so on. A large number of coordinations need to be calculated for position with total station instrument or GPS-RTK. But since more complicated spiral curves are applied to the modern route design, traditional methods of coordination calculation become more and more diffcult. Combining with actual conditions,it analyzes the characteristics of different spiral curves and proposes the methods of coordinate calculation which all coordinations are based on first point of tangency and all the calculations are unified in the method.
