摘要
针对异形建筑物传统施工放样过程操作复杂、效率低下的问题,该文提出了采用GPS RTK进行异性建筑物施工中的放样工作。以天津市文化中心商业项目为例,利用GPS RTK技术分别对建筑物的主轴线和异形次轴线进行了放样工作,并与全站仪在放样过程和数据精度两个方面进行了对比分析,实现了异型建筑物快速、高效的施工放样。实验结果表明,GPS RTK技术不仅在放样过程中操作简单,节约资金,而且放样精度满足工程要求,相对全站仪来说具有很大优势,有助于提高复杂异形建筑物的施工放样效率。
Aiming at the problem that the abnormity buildings are complicated and inefficient in the traditional construction lofting process,this paper presented a method to solve them by the GPS RTK technology.Taking cultural center in Tianjin commercial project as an example,GPS RTK technology was respectively used the main axis and the abnormity time axis layout work of the building,which was compared and analyzed with the total station in two aspects of the lofting process and data precision realizing the abnormity buildings rapid and efficient construction lofting.Results showed that the GPS RTK technology not only in the lofting process simple operation,and lofting precision meet the engineering requirements,relative to the total station has great advantages,which was conductive to improve the efficiency of complex abnormity buildings construction lofting.
