桥梁工程信息模型分类与编码研究

Research on Classification and Coding of Bridge Information Modeling

BIM技术作为近年来工程创新发展的新技术,在公路行业的应用越来越广泛,桥梁工程作为公路项目的重要组成部分,具有参与方众多、结构形式复杂、信息量大等特点。在全生命周期内如何实现桥梁工程的不同参与方与异构系统之间对信息的理解一致,就非常重要。分类编码标准作为BIM技术标准之一,即语义标准,其作用就是解决语义信息的共享问题。将基于公路工程信息模型分类与编码标准的研究框架内,分析国内外桥梁工程信息分类编码标准的现状和存在的问题,总结出构造物、空间结构、构件、属性和材料等5张分类表桥梁专业的详细内容,并从运算符应用、编码应用、IFC中应用和项目应用等4个方面研究分类编码的应用,为桥梁工程信息模型分类编码提供有力支撑。

As a new engineering technology of innovation and development in recent years,BIM has been applied in highway industry more and more widely,meanwhile,as an important part of highway project,bridge project has many characteristics such as numerous participants,complex structure and large amount of information.It is very important to realize the uniform understanding of information between different participants and heterogeneous systems of bridge engineering in the whole life cycle.As one of BIM standards,the standard for classification and coding is to solve the problem of sharing semantic information.In this paper,based on the research framework of standard for classification and coding of bridge information modeling,the present situation and existing problems of information classification and coding standard of bridge engineering in China and abroad are analyzed,the details of the bridge in terms of function,form,structure,component,attribute and materials are summarized,and the application of classification and coding is studied from four aspects of operator application,coding application,IFC application and project application,which provides strong support for the classification and coding of bridge information modeling.
