基于BIM+GIS的运营重载铁路隧道快速建模与信息集成技术

Rapid Modeling and Information Integration Technology for Operating Tunnel of Heavy Haul Railway Based on BIM+GIS

目前各类BIM(建筑信息模型)建模软件中隧道构件库仅具有存储和展示管理功能,无法与实际构件后期应用进行信息交互,极大影响了构件库的应用价值。本文首先确定了隧道构件的编码方式,然后探讨了运营重载铁路隧道BIM快速构建技术和基于BIM+GIS(地理信息系统)的隧道设备服役状态信息集成方法,构建了隧道构件库,建立了典型隧道地质模型和结构模型,开发了隧道地质模型、结构模型、倾斜摄影模型与GIS图像的融合技术;最后根据朔黄铁路现场实测数据开发了重载铁路隧道设备BIM+GIS展示平台。研究成果可为重载铁路隧道设备智能管理提供借鉴。

The current tunnel component libraries in various BIM(Building Information Modeling)modeling software only have storage and display management functions,and cannot interact with actual components in the later stage,greatly affecting the application value of component libraries.In this paper,the coding method of tunnel components was determined,the rapid construction technology of BIM for operating tunnels of heavy haul railway and the integration method of tunnel equipment service status information based on BIM+GIS(Geographic Information System)were explored,the tunnel component library was constructed.The typical tunnel geological and structural models were established,and the fusion technology of tunnel geological models,structural models,oblique photography models,and GIS images were developed.The BIM+GIS display platform of heavy haul railway tunnel equipment was developed according to the field measured data of Shuozhou-Huanghua railway.The research results can provide useful reference for the intelligent management of heavy haul railway tunnel equipment.
