针对目前城市地下综合管廊二维管理模式存在的直观性差、效率低问题,采用 BIM技术,对综合管廊构件进行编码和族库构建.在此基础上,提出了综合管廊结构主体模型、入廊管线模型和附属结构模型的参数化建模方法,实现了管廊模型的快速生成,有效地提高了建模效率.基于 C#编程语言、数据库技术、Revit、Unity平台和 Dynamo 的二次开发技术,开发了地下综合管廊建模平台,实现了综合管廊模型的有效集成、信息查询和三维漫游展示,解决了地下综合管廊可视化运维管理的关键问题,为地下综合管廊整体可视化运维管理奠定了良好的基础.
Modeling and System Implementation of Urban Underground Utility Tunnel Based on BIM Technology
In view of the existing problems of poor visibility and low efficiency of current two-dimen-sional management model of urban underground comprehensive corridors,BIM technology was adopted to encode the components of the comprehensive pipe gallery and build a family library.On this basis,a parameterized modeling method was proposed for the main model of the comprehensive pipe gallery structure,the inlet pipeline model,and the auxiliary structure model,which achieved rapid generation of the pipe gallery model and effectively improved modeling efficiency.By using C#programming lan-guage,database technology,Revit,Unity platform,and secondary development techniques of Dynamo,a modeling system for underground integrated pipe corridors and an underground utility tunnel modeling platform has been developed.This platform achieved effective integration of the utility tunnel model,information query and provided three-dimensional roaming display,which addressed the key issue of visual-ized maintenance and management of the underground utility tunnel.The research achievements established a good foundation for the overall visualized maintenance and management of the underground utility tunnel.
