摘　　要：海口南光中心项目基坑周边场地狭小,需要尽快完成地下室施工,实现施工场地平面部署由基坑周边向地下室顶板的转换。通过无人机航拍制作桩基场地正射影像,并经矢量化等技术处理后批量计算获取桩位偏差数值,测量作业人员及工作时间均少于传统工作模式,为缩短地下室施工周期提供技术借鉴。The surrounding area of the foundation pit of Haikou Nam Kwong Centre is narrow,and the basement construction is required as soon as possible to achieve the conversion of the construction site plane deployment from the surrounding of the foundation pit to the basement roof.UAV is used to make orthophoto images of pile foundation site by aerial photography,and the pile deviation values are obtained by batch calculation after processing by techniques such as vectorization,which reduces the surveying labor cost and operation time compared with the traditional working mode,and makes a partial contribution to shorten the construction cycle of basement.
