置镜任一点极坐标法测设曲线精度分析

ACCURACY ANALYSIS ON CURVE-LAYOUT BY POLAR CO-ORDINATES METHOD WITH SURVEYOR'S TABLE AT ARBI-TRARY PLACE

本文对置镜任一点，光电测距仪（或全站仪）极坐标法测设曲线所产生的误差进行了详细分析，同时给出了从控制点引测测站的最佳方式，测站上的最大测线长度以及曲线测设工作中应注意的一系列问题。

A curve-layout is usually made by polar coordinates method with optical ranging onsurveyor s table placed at arbitrary point in field.The errors produced by this method are ana-lyzed in detail in this paper.Meanwhile,the author suggests the best means in which the survey-ing-station is inspected from the control point,the maximum,length of measuring line on the sur-veying-station and a series of prblems that should be paid attention to the curve-layout works.
