Application Analysis of Three Dimensional Scanning Technologies in Tunneling Engineering

Aiming at the application and promotion of three dimensional laser scanning imaging technology in tunnel construction, especially applicability in the special and complex environmental condition of tunneling engineering, the paper studies the application of three dimensional laser scanning imaging technology in the process of tunnel construction. Through recombination and anatomy of data acquisition of scanner, the data processing and the processing result appraisal analysis, with a combination of request and the critical control points of tunneling excavation and timbering, it points out the content and the method of promptly and accurately executing high-precision data acquisition as well as the starting point of carrying out target-oriented data processing and comparison. It clarifies the tasks of testing blasting, judging geological conditions, providing bases of analyses, calculating the number of construction, comparing monitoring dynamic. The practice of the construction shows that the technology has a very high value of application and promotion in tunnel construction.
