摘　　要：道路平面综合曲线坐标的计算是工程测量中比较复杂的一个问题,文中提出了交点法和要素法两种计算方法。交点法适用于特定结构的综合曲线,精度高;要素法适合于任何结构的道路曲线,比较灵活,但容易产生误差累计,可通过强制纠正的办法进行应对。文中对两种方法的实现进行了探讨,并在Excel VBA中开发出了相应的计算程序。In the paper,the author puts forward two calculation methods which are the intersection of law and the elements of law because the calculation of road surface curve coordinates is the more complex problem in engineering survey.The intersection of law is high precision applying to the specific structure curve,the elements of law is more flexible applying to the any structure road curves,but it is prone toerror accumulation which can be forced to correct method to deal with.The author discusses the two methods and develops the corresponding computer program in Excel VBA.
