摘　　要：为提高湖北省十堰市聚仙庙水库建设期现场地质勘察智能化水平,并为其导流洞支护优化设计提供准确的地质资料,利用SLAM三维激光扫描仪对导流洞开展围岩编录工作。使用ZEB Horizon扫描仪搭配ZEB Vison全景相机进行数据采集,并在进行三维点云扫描的同时拍摄全景照片。将扫描数据导入长岩实景三维地质编录软件,融合匹配激光点云和全景照片,生成现场实景三维视图,在实景视图下开展地质编录工作,最终得到导流洞的围岩地质编录图和结构面编录数据表。实践结果表明:使用SLAM技术开展地质扫描和实景编录可减少现场工作时间,提高整体工作效率,具有一定的推广价值。In order to improve the intelligent level of on-site geological survey data during the construction period of Juxianmiao Reservoir in Shiyan City,Hubei Province,and provide accurate geological data for the optimal design of diversion tunnel support,SLAM 3D laser scanner was used to catalog the surrounding rock of the diversion tunnel.The ZEB Horizon scanner was used with the ZEB Vison panoramic camera for data acquisition and the panoramic photos were taken at the same time as the 3D point cloud scanning.The scanned data was imported into ChangYan real-scene 3D geological cataloging software,integrated and matched with laser point clouds and panoramic photos to generate a real-scene 3D view of the site.The geological cataloging work was carried out under the real-scene view,and finally the surrounding rock geological cataloging map and structural plane cataloging data table of the diversion tunnel were obtained.The results of application practice showed that the use of SLAM technology to carry out geological scanning and real-world cataloging can reduce the on-site working time and improve the work efficiency,which has a good value for promotion.
