Investigation and Analysis of High Slope Dangerous Rock at the Entrance of Siguxi Tunnel Based on UAV Photogrammetry
摘要
Abstract
The high slope dangerous rock at the entrance of Siguxi Tunnel has the characteristics of high position and strong concealment.It is difficult to investigate the dangerous rock mass.The UAV digital photogrammetry technology is used to construct the real three-dimensional model by using the Pix4dmapper software,and 13 dangerous rock mass structures are extracted and determined in the model.Rockfall software is used to simu-late the collapse motion characteristics of typical dangerous rock mass,and it is found that it has great harm to the tunnel portal and the subgrade outside the tunnel portal.关键词
