建筑物的定位放样方法及其误差分析

On positioning and sampling method of buildings and error analysis

鉴于建筑物定位的点位放样精度和放样方案的选择在整个建筑工程的施工过程中占有重要的地位,首先分析了建筑物定位放样的精度要求,然后讨论了极坐标法和角度交会法放样的误差问题,从而为建筑工程进行定位放样时合理的选择放样方案奠定了基础。

As the selection of the point positioning of buildings and sampling scheme as the important role in the construction process of the whole architectural projects,the paper analyzes the accurate requirement of the positioning and sampling of the buildings,discusses the error problems in the polar coordinate method and the angle intersection method,so as to lay the basement for selecting reasonable positioning and sampling schemes in the architectural engineering.
