摘要随着国家对基础设施投资力度的加大,线路设计及测量放线任务与日俱增。在公 路、铁路、地铁隧道、轻轨等线路工程中，都离不开圆曲线的放样，由于受到地形、 地物、地质及其他因素的限制，经常需要改变线路前进的方向，并且使用不同的放样 方法进行测设。当线路中线由一直线方向转变为另一直线方向时，或由一坡度转变为 另一坡度时，为保证运行安全，一般在水平方向和竖直方向均设置一定半径的圆曲线。73970

论文主要介绍水平方向圆曲线测设。圆曲线的测设方法有很多，本文在分析相关 资料的基础上，主要对全站仪直接放样法、全站仪自由设站法、偏角法、切线支距法、 极坐标法以及 GPS RTK 法等多种测设方法进行详细阐述，并从多角度出发，对上述 测设方法加以比较。

Abstract With the increase of the country's investment in infrastructure, the design and measurement of the line is increasing day by day。 In the highway, railway, subway, light rail and other line project, are inseparable from the circular curve lofting, due to the limitation of topography, terrain, geology and other factors, often need to change the direction of the forward line, and the use of different lofting method for survey and design。 When the line by line direction into another line direction, or by a slope change is another slope, in order to ensure the safe operation, general in the horizontal direction and the vertical direction are set the radius of circular curve。

This paper mainly introduces the measurement of horizontal circular curve。 Circular curve survey and design method has a lot of, this paper in the analysis on the basis of relevant information, mainly of total station instrument layout method, total station free design station method, method of deflection angle and tangent distance method, polar coordinate method, chord very coordinate method, the outer circle of the very coordinate method, as well as GPS-RTK method and a variety of test design methods described in detail and from multiple perspectives of the test design methods were compared。

Key words：Circle curve Test setting method compare
