摘　　要：结合古交市西曲汾河大桥施工放线的实例,介绍了两种曲线坐标计算方法,即切线支距法和圆心偏角法,通过对比分析,选出一种比切线支距法更简捷和不容易出错的计算坐标的新方法——圆心偏角法。By combining with example of the construction line-putting of Xiqu Fen river Bridge in Gujiao city, the paper introduces two kinds of curve coordinate calculation method, that is tangent offset method and the center declination method, according to comparison analysis and chooses a new method, center declination method which is easier to operate than the tangent offset method and makes less mistakes.

关 键 词：坐标计算 曲线 切线支距法 圆心偏角法
