全站仪坐标法施工放样技术在建筑工程领域中的应用

Application of Coordinates of Setting-out Survey using Electronic Total Station in Architectural Engineering Field

常用的传统施工放样方法有角度交会法、距离交会法、极坐标法等,这些方法通常使用普通测量仪器和工具进行,也能够满足工程建设精度要求,不足之处是测量人员的外业工作强度大、劳动效率低,精度也受到一定限制。随着建筑工程向高层超高层、大跨度、深基础、建筑形体越来越复杂等方向发展,工程施工无论在技术难度还是精度要求上,对施工放样提出了越来越高的要求,同时测量技术也在不断发展和进步,测量仪器设备在不断更新,特别是全站仪的研制成功和应用,给测绘领域带来了革命性的变化,给测量人员带来了福音,施工一线的广大技术和管理人员也迫切希望能够将先进的测量技术应用到工程建设领域,数字化测设方法无疑是一种好的选择。

Commonly used traditional Construction setting-out survey methods including angular intersection,linear intersection linear-angular intersection and so on.These methods typically use common surveying instruments and tools,and the data is also able to meet the precision of engineering construction requirement,however,due to the intensive field work,low labor productivity,the accuracy is subject to certain restrictions.As the building developed to high-rise structure,long-span,deep foundations,and the shape becoming more complex,construction both in technical difficulty and precision requirements on survey put increasingly higher demands for the setting-out survey.This paper discussed the application of coordinates of setting-out survey using electronic Total Station in architectural engineering field.
