摘要
地铁盾构区间常穿越城市主城区,人流、车流、建筑物多而密,地面沉降监测采用常规钻孔埋点的人工监测模式工作量大、时效性差,且受布点间距影响存在无法反映大沉陷变形甚至坍塌事故预警的风险。论文提出基于车载激光雷达的面状扫描的特性,利用控制标靶点进行三维坐标纠正,来快速实现对城市道路面状沉降监测的防坍塌应用探索。
The subway shield tunneling section often passes through the main urban area,with a large and dense flow of people,vehicles,and buildings.The manual monitoring mode of using conventional drilling and burying points for ground settlement monitoring is labor-intensive and has poor timeliness.Moreover,due to the influence of point spacing,there is a risk of not being able to reflect large settlement deformation or even collapse accident warning.This article proposes the exploration of anti collapse applications for urban road surface settlement monitoring based on the characteristics of surface scanning using vehicle mounted LiDAR,using control target points for 3D coordinate correction.
