Research on Key Process Elements and Automatic Judgment Technology of High-Speed Rail Drilling and Blasting Tunnel
The construction processes of high-speed rail drilling and blasting tunnel are complex and difficult to control.At present,the time duration of each process is usually counted in the form of manual record that features non-timeliness,untimely feedback and low progress control accuracy.This paper analyzes the business scenarios and digitalization of high-speed rail drilling and blasting tunnels,analyzes the key process business and data elements,and innovatively proposes the automatic identification technology of key processes of high-speed rail drilling and blasting tunnels,and forms a set of automatic identification software and hardware equipment,which provides necessary technical means for automatic data acquisition and intelligent process analysis,so as to improve the management level of tunnel engineering.
