摘要
Abstract
Due to the limited construction environment and complex geological conditions of the deep and long inclined shaft soft rock tunnel,in order to improve the efficiency of monitoring the initial support deformation data of the tunnel,solve the problems of small amount of traditional monitoring data,low visualization level,and low data utilization rate,3D laser scanning technology is applied to the deformation monitoring of the deep and long inclined shaft.3D point cloud processing software Geomagic Studio is used to process the actual section point cloud contour and compare it with the tunnel design contour data to analyze its deformation situation.3D laser scanner has a high sampling rate and can accurately and quickly reflect the real and complex conditions of the tunnel.It is compared and demonstrated with traditional monitoring instruments such as total stations in terms of measurement and trend.The results show that the monitoring results are basically consistent,which can provide data support for determining the deformation level of the tunnel,evaluating safety construction,and optimizing the tunnel support system.关键词
