Abstract

Abstract:

At present, problems such lack of unified exchange standards, difficult spatial analysis and attribute query of 3D CAD and difficult integrated display of data exist in engineering geological data in rock tunnels. Hence, by taking Laoying Tunnel in Yunan for example, analysis is carried out as follows: (1) The catalogue and information node of engineering geological information in rock tunnel is put forward to realize efficient and rapid engineering geological data classification. (2) The CAD data is changed into GIS data from 4 formats of point, line, surface and text annotation, so as to solve the deficiency of CAD data in spatial analysis and attribute query. (3) Some engineering geological data of Laoying Tunnel are classified and processed and compositively displayed in infrastructure smart service system iS3. The final results show that the proposed method can improve the management level of the engineering geological data of the Laoying Tunnel and provide reference value for the engineering geological data management in similar project in the future.

Key words: rock tunnel, engineering geological data, data classification, data management, iS3
