摘　　要：主要讨论了采用Photogrammetry技术监测地下施工过程中地表变形的主要方法和应用情况。地表变形过大往往会导致地表既有建筑物的破碎,所以量化监测其变形程度在地下施工中尤为重要。Photogrammetry技术是一种非接触式的变形监测技术,主要通过影像手段获取目标点的三维变形大小。该方法需要从空间多角度对目标点进行摄影测量,获取连续的三维影像信息,通过Photogrammetry软件进行现场目标点重现,进而获取三维可视目标点坐标值。本文通过现场的监测,获取了地表变形的数据,提出了监测的方法。This paper discusses the application of photogrammetric technology to monitor ground movements associated with underground constructions.Ground movement is a concern of underground construction due to that it can cause damage to surface structures and buried utilities.Photogrammetry is a remote technology in which the 3D properties of objects and surface can be determined from images.coordinates of the target are determined by different photographs taken from different positions and the targets shouldn＇t be moved during the measurements.The photogram metric software can be used to determine the position of these targets in 3D space.This paper provides an overview of photogrammetric technology,its application to underground projects,results and analysis of data gathered from measurement.
