基于三维激光扫描技术的顶管施工邻近路面沉降变形监测

Monitoring of Pavement Settlement and Deformation Adjacent to Pipe Jacking Construction Based on 3D Laser Scanning Technology

摘要:

随着城市的发展，地下空间开发工程数量日益增多，施工中下穿城市快速路的情况也越来越多，但由于快速路车速快、车流量大且一直处于通行状态，传统的监测方式无法满足施工监测的需求。利用三维激光点云扫描技术获取S20路面整体三维点云数据，通过不同时段的点云数据比对获取路面沉降变形情况，为施工中的路面沉降变形监测提供一定的数据支持，也为以后的工程监测提供新的技术方法。

Abstract:

With the development of cities, the number of underground space development projects is increasing day by day, and the situation where construction passes under urban expressways is also becoming increasingly common. However, due to the high speed, large traffic volume and constant traffic on expressways, the traditional monitoring methods cannot meet the needs of construction monitoring. The 3D laser point cloud scanning technology is used to obtain the overall 3D point cloud data of S20 pavement, and the settlement and deformation of pavement are obtained through the comparison of point cloud data at different periods, which provides certain data value for the monitoring of pavement settlement and deformation during construction, and also provides a new technical method for the engineering monitoring in the future.
