岩石隧道工程地质数据分类管理与应用

目前岩石隧道中工程地质数据缺乏统一交换标准、二维CAD 数据不便于进行空间分析和属性查询、数据难于集成显示等, 为解决以上问题,基于云南省老营隧道工程,提出岩石隧道工程地质信息目录和信息节点,实现对工程地质数据进行有效、快速的分类; 将CAD 数据以点、线、面、文字注记4 种格式转换成GIS 数据,解决不同CAD 数据在空间分析、属性查询方面的欠缺; 对老营隧道部分工程地质数据进行分类和处理,并在基础设施智慧服务系统iS3 中进行集成展示。最终结果表明,本文提出的方法提高了老营隧道工程地质数据的管理水平,对类似岩石隧道工程中地质数据管理有一定借鉴价值。

Classification Management and Application of Engineering Geological Data of Rock Tunnel

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.
