IFC标准下隧道智能管理系统建立与应用

Establishment and Application of Tunnel Intelligent Management System Under IFC Standard

建筑信息模型(BIM)是一种有效的复杂工程信息综合管理方法,为了实现隧道类岩土工程信息在BIM模型中进行清晰、规范表达的目的,将IFC标准文件针对隧道领域进行相应拓展,实现了不同平台之间信息无损交互传递。通过参数化族建模方式创建隧道构件族库,采用坐标定位的形式拼装隧道工程模型,并将所建立的模型参照IFC拓展标准进行实体及属性定义。基于BIM模型中所整合的工程信息,开发计算功能模块,分别实现了监测数据整合与预警、隧道围岩分级评价与工法推荐、岩体参数反分析、BIM模型的数值计算评价等信息处理功能,形成IFC标准下隧道智能管理系统。将所建立的系统方法依托甄峰岭隧道工程进行应用调试,取得了良好的工程适用效果,为类似岩土工程信息化施工体系的建立提供了一种新思路。

Building Information Model(BIM)is an effective comprehensive management method for engineering complex information.In order to clearly and standardize the tunnel geotechnical information in the BIM model,the IFC standard file is expanded for the tunnel field,and the information is transmitted without loss of interaction between different platforms.The tunnel component family library is created by parameterized family modeling.The tunnel engineering model is assembled in the form of coordinate positioning,and the established model is defined by the IFC extension standard for entity and attribute definition.Based on the engineering information integrated in the BIM model,the calculation function module is developed to form the tunnel intelligent management system under the IFC standard,which realizes the information processing functions such as monitoring data fitting prediction,tunnel surrounding rock classification evaluation and construction method recommendation,rock mass parameter inverse analysis,BIM model numerical calculation evaluation,etc.To verify it s reliability,the established system method is applied and debugged according to the Zhenfengling tunnel project,and has achieved good engineering application results,which provides a new idea for the establishment of geotechnical engineering information system.
