导线极坐标法测设道路曲线方法研究与应用

Research and Application of Surveying Road Curve in Wire Polar Coordinate Method

概述了道路测设概况及特点,提出了导线极坐标测设法详细测设圆曲线的方法。并以阜新东梁矿附近铁路缓和曲线的中线及横断面实测为例,介绍了道路工程几种曲线及其基本要素,分析了在测量前要进行计算的数学模型,研究了全站仪导线极坐标法放样的基本步骤以及操作方法,具体介绍了导线极坐标法测设曲线的方法。实践证明,导线极坐标法测设圆曲线的方法是一种非常实用的方法。

This article through the narrative of the road survey in general situation and characteristics put forward the method of wire polar coordinates measuring circular curve in detail. It takes east mine in Fuxin near the railway the centerline of the curve and crosssectional measuring for example,knowing about the road projects,several curve and its basic elements,before measuring familiar with the mathematical model of the calculation,studying the basic step and operation method of total station wire polar coordinate method. A comprehensive grasp of wire polar coordinate surveying curve method. From the practice we can summarize wire polar coordinate survey in the circular curve method is a very practical method.
