摘　　要：线定向设站是指全站仪任意设站后,分别测量两个特征点,并以第一个点为坐标原点,第二个点为X轴或Y轴方向,建立独立坐标系并解算测站空间坐标及方位角的设站方法,通过该方法可方便测量出空间特征点至某铅锤面的垂直距离。以徕卡TS60全站仪为例,本文介绍了线定向设站的作业流程及方法,对设站建立的独立坐标系的模型进行了探讨,并以某厂房内单梁桥式起重机两根平行钢轨的变形测量为例,介绍了该方法在工程测量中的应用。Line orientation station is a method to set up the coordinate system and calculate the space coordinate and azimuth angle of the station by measuring two characteristic points separately after the station seted up by the total station.Take the first point as the origin of coordinates and the second point as the direction of X-axis or Y-axis,set up the coordinate system and calculate the space coordinate and azimuth angle of the station.The vertical distance from the space characteristic point to a lead hammer surface can be easily measured by this method.Taking Leica TS60 total station as an example,this paper introduces the operation flow and the method of line orientation station,and analyzes the precision and influencing factors of station setting.Taking the deformation measurement of two parallel rails of a single beam overhead crane in a factory building as an example,the application of this method in industrial survey is introduced.
