application of laser in highway engineering journals

Combined with the data storage and backup requirements of highway toll collection system, such as large amount of information, high reliability, easy management, and easy management, a complete design scheme of optical storage backup chip based on programmable logic array. Experimental comparisons and analyses of the laser scanning method against conventional surveying techniques are also considered. In order to improve the efficiency and accuracy of retrieval and mining of highway operation management information, a digital method research and application method based on laser scanning technology is proposed. An additional example of the use of the method in the geometric documentation of the concrete lining formwork is examined and comparisons against dimensional tolerances are examined. Particularly, the potential of the method is examined for checking the tunnel profile, producing volume computations and validating the smoothness/thickness of shotcrete layers at an excavation stage and during the completion of excavation support and primary lining. Specific case studies are considered based on two construction sites in Greece. Also, it discusses the planning, execution, data processing and analysis phases of laser scanning activities, with emphasis given on geo-referencing, mesh model generation and cross-section extraction. It provides a detailed overview of the static laser scanning method, its principles of operation and applications for tunnel construction operations.

This paper discusses the use and explores the potential of laser scanning technology to accurately track excavation and construction activities of highway tunnels. The 3D laser scanning measurement technology can quickly achieve the &x201c copy&x201d measurement of the target, especially suitable for the digitization of complex structure and the accurate construction of true 3D model and it takes care of. Particularly, this is of great importance in the underground space and tunnel construction environment as surveying engineering operations have a great impact on both technical and economic aspects of a project. The rise of heteromorphic architecture brings great challenges to engineering design, blanking, construction, completion testing, and maintenance. Driven by progress in sensor technology, computer software and data processing capabilities, terrestrial laser scanning has recently proved a revolutionary technique for high accuracy, 3D mapping and documentation of physical scenarios and man-made structures.
