摘要
介绍了缓和曲线和圆曲线的中、边桩坐标计算公式,讨论了曲线在各种情况下的坐标变换公式及如何利用方位角进行曲线偏向的判断,给出了曲线任意点方位角的详细计算公式,并分别结合PC-E500S和VC进行了程序设计。
The paper introduces the formuas of calculating of middle piles and sides piles in road curves. The coordinate transforming formulas of curve in every situation, and how to estimate the deflection of curve using azimuth angle are discussed, and the particular calculation formulas of azimuth angle on curve are givenand . Besides, the programs are designed in Visual C++ and on PC-E500s.
