摘　　要：传统的公路曲线测设的方法有切线支距法、偏角法等,这些传统方法都是先测设出曲线各主点后再进行详细测设,通常会受到实地地形限制,因此需要寻求更方便快捷的方法。随着计算机和全站仪的普及和推广,尤其是GPS定位仪的开发,改变了以往工程技术人员大量、繁复的分析计算工作方式,极大地提高了工作效率和质量。曲线测设程序在测设工作中能够快速、高精度地计算线路上的一切数据,配合全站仪工作,充分发挥便携式计算工具的作用,满足高精度快速测设的需要。本文重点讨论了曲线测设程序的设计原理、过程及其在线路测量中的应用,并指出了该程序的不足和需要改进之处。There are many methods to highway curves location , traditional methods such as tangent off -set method and method of de-flection angle .These methods are all locating the main points of the curves first , and then conducting the details location .Since they are usually limited by the field topography , we need to find a convenient method .As the Total Station and computer are popularized and promoted, a variety of computing tools replace large and complex analysis work for engineering and technical personnel to greatly improve the efficiency and quality of work .Procedures for curve location can compute all data of lines rapidly and high precise , work-ing with the Total Station , gives full play to the role of portable computing tools and meets the needs of fast high -precision measure-ment.This article focused on the design principles and process of location procedures , as well as its application to line measurement . And pointed out the inadequacy of the procedures and areas for improvement .
