摘　　要：在工程测设曲线的长期实践中,发现了一种简易实用的方法——短弦中垂距法。经采用科学的原理分析,在理论上是成立的。该方法使用工具简易,测设方法步骤易学易懂。对短弦中垂法的测量原理及测量方法和步骤进行了论述。实践证明,在地形复杂和量距困难的地区,利用短弦中垂距法进行圆曲线测量,是一种好的方法。In the long-term practice of engineering survey and layout curve, a simple and practical approach -- Short String Middle Perpendicular Offset Method is developed. Through scientific theory analysis, it is proved to be true theoretically. This method uses simple tools, and easy to learn and to understand the steps of survey and layout. The principle, method and steps of the measuring method are expatiated. And practical application shows that method can be used for the survey and layout of circular curve in areas with complicated topography.
