极坐标放样法在曲线中线桩测设中的应用

摘要

This paper introduces the polar setting-out at any point set up the principle and method of middle pile layout curve , make full use of the advantages of total station and the programmable calculator, can set a station layout for many times, the law has the sta-tion choose flexible, fast layout and lofting point precision higher advantages, is a kind of very good lofting method.%介绍了极坐标放样法在任意点设站测设曲线中线桩的原理和方法，充分利用全站仪和可编程计算器的优点，可一次设站多次放样，该法具有测站选择灵活，测设速度快，放样点位精度高等优点，是一种很好的放样方法。
