摘　　要：对目前铁路曲线测设的切线支距法、偏角法、极坐标法进行对比、分析 ,融合各种测设方法的优点 ,提出一种广泛适用的弦切法 ,可以任选支镜点 ,适用各种地形条件下的曲线测设。在内业工作量增加不多的情况下 ,降低了外业工作量 :减少了支镜点数量 。Chord tangent method,which is widely applicable,is proposed which integrates the advantages of different methods of measurement and design.This method can be applied to the curve measurement and design of a variety of terra forms. It can reduce outdoor working load and is helpful in improving the accuracy of measurement.

关 键 词：曲线测设 弦切法 铁路测量
