【摘要】：随着我国经济的发展,桥梁建设也如火如荼地展开,一些世界级的钢桁架桥梁不断在我国西南地区相继上马。这些工程规模大、投资多、施工难度大,在实际工程设计和管理过程中,迫切需要确定合理的施工方法、优化施工配套机械、制定切合实际的施工进度计划对工程进行高效简洁的管理,从而保证桥梁工程的顺利开展和工程成本的降低。随着计算机技术的不断发展和管理理念的不断更新,BIM技术以凸显的理念应用于建筑寿命周期(BLM)的各个阶段,从而引发越来越多的关注。BIM技术的核心在于给予三维模型以完整的信息流,覆盖建筑全生命周期的每一个阶段。通过和三维模型的交互,设计信息、施工信息、制造安装信息等通过分类数据库以及动态关联直接呈现于用户面前,便于检查、修改、维护、管理,实现模型信息资源的全局共享。本文将BIM和BLM理念引入到钢桁架桥梁的设计和施工仿真当中,提出钢桁架桥梁的信息模型-STBrIM(Steel Truss Bridge Information Model).STBrIM根据钢桁架桥梁的结构特点,利用数据库技术,提出各种杆件和节点的信息模型和数据图形融合技术,并依此为基础信息单元进行延拓,将设计、施工、管理阶段的信息进行分类,归并为不同的数据库单元,在桥梁构筑的不同阶段供使用者进行权限调用,以此避免了传统设计中的“信息孤岛”效应。以Inventor作为平台开发STBrIM的仿真系统,该系统运用本文提出的钢桁架桥梁的的基本概念,在轴线的基础上模拟设计、施工、管理等各个环节,使钢桁架桥梁在构筑的全生命周期内共享同一套三维模型,实现中心数据库控制下的信息模型一处修改,处处修改,有效解决各种不同阶段、不同工种之间的信息沟通问题。并将本文开发的系统用于实际工程当中,取得较好效益。
[Abstract]:With the development of China's economy, the bridge construction also spread like a raging fire, some of the world's steel truss bridge in Southwest China have been launched. These projects are large in scale, high investment, difficult construction, in the design and management process in the actual project, the urgent need to determine the reasonable construction method, optimization of construction machinery the construction schedule, making the practical for simple and efficient management of the project, so as to ensure the smooth development of the bridge engineering and reduce the project cost.
With the continuous development of computer technology and the constantly updated management concept, to highlight the concept of BIM technology applied in building life cycle (BLM) phases, which caused the attention of the core.BIM technology more and more is given to complete the three-dimensional model of information flow, each stage covers the whole life cycle building. Interaction and, through the three-dimensional model of design information, information construction, manufacturing and installation information through classification database and dynamic association directly in front of the user, easy to check, modify, maintenance, management and sharing of information resources in the global implementation model.
This paper will introduce the concept of BIM and BLM to design and construction simulation of steel truss bridge, puts forward the -STBrIM information model of steel truss bridge (Steel Truss Bridge Information Model.STBrIM) according to the structural characteristics of steel truss bridge, using the database technology, the fusion of information model and data graph of members and joints, and so the basic unit of information extension, design, construction, management information classification, merge into database unit different, in different stages of building a bridge for a user to access the call, in order to avoid the traditional design of the "information island" effect.
Using Inventor as the simulation platform of STBrIM development, the basic concept of the system is the use of steel truss bridge is presented in this paper. The simulation based on the axis of the design, construction, management, the steel truss bridge share the same set of three dimensional model in the construction of the whole life cycle, the realization of information center database control model under an amendment, everywhere modified, effectively solve the various stages of information communication problems between the different types of work. And this system is used in practical engineering, to achieve better efficiency.
