In view of the problems
existing in current tunnel construction information monitoring, such as low
automation levels, independence of equipment, diversified and heterogeneous
data, and low reliability, the intelligent acquisition method of multifaceted information
such as tunnel face geology, surrounding rock-structural deformation, and refined construction is studied, the
information intelligent analysis algorithm based on binocular vision-grid structured light, video image depth segmentation network, and
other technologies is proposed, and the integrated intelligent perception
equipment for multifaceted information of tunnel face is developed. Field tests
and applications have been carried out in tunnels such as Huayingshan tunnel of
Xi′an-Chongqing high speed
railway. The results indicate that: (1) In the challenging conditions of tunnel
face construction areas, this technology and equipment can accurately and
reliably collect geological, deformation, and construction information in real time.
(2) Compared to traditional methods, the system significantly enhances the
integrity, efficiency, accuracy, and reliability of the collected information.
This improvement provides essential data support for ensuring tunnel
construction safety and advancing the intelligent construction level of railway
tunnels.
