【摘要】：BIM(Building Information Modeling,建筑信息模型)近年来成为了工程领域的一大热点,但桥梁工程中的BIM技术应用研究,仍处于初步阶段,相关实例较少,应用模式及方法目前正处在探索阶段。尼尔森体系系杆拱桥的主要特点为斜吊杆布置,结构形式复杂,施工方案的合理规划十分重要。本文结合128m尼尔森体系系杆拱桥拱肋及吊杆的施工过程,研究了BIM技术在桥梁施工中的应用方法,主要内容包括:(1)首先研究了BIM的发展背景及国内外发展、研究现状,阐述了BIM的基本概念、内涵和特点,以及与二维CAD技术的差异,总结了BIM的实现方法和目前我国BIM发展的现状以及存在的一些障碍。(2)针对桥梁工程施工中结构复杂、施工环境复杂和“粗放型”管理模式等现状带来的问题,结合BIM技术的基本特点,研究了桥梁工程施工中基于BIM的施工技术和管理方法。经研究分析发现,BIM技术可以有效的提高桥梁工程施工的技术和管理水平,在一定程度上提高施工效率,使管理做到精细化,在一定程度上解决了目前桥梁工程施工中的一些问题。(3)针对尼尔森体系系杆拱桥的BIM模型建立,试用了Autodesk Revit和Bentley平台下的软件,最终选取Bentley作为尼尔森体系系杆拱桥的BIM软件。并建立了系杆拱桥结构模型、拼拱支架模型及场地模型。(4)借助于Bentley软件以及建立完成的模型,对尼尔森体系系杆拱桥的拱肋拼装及吊杆安装进行了施工方案设计、场地模拟、4D进度模拟及数字化建造等应用研究,实现了BIM技术在施工中的应用。研究成果有助于行业内其他类似项目的应用研究,可在其他项目的施工实例中起到一定参考作用。
[Abstract]:BIM (Building Information Modeling, (Building Information Model) has become a hot spot in the field of engineering in recent years, but the application research of BIM technology in bridge engineering is still in the initial stage, there are few related examples, and the application modes and methods are now in the exploration stage. The main features of Nielsen system tied arch bridge are the arrangement of slanting suspenders, the complexity of structure form, and the reasonable planning of construction scheme is very important. Combined with the construction process of arch rib and suspender of 128m Nielsen system tied arch bridge, the application of BIM technology in bridge construction is studied in this paper. The main contents are as follows: (1) the development background of BIM and the development at home and abroad are studied. This paper expounds the basic concept, connotation and characteristics of BIM, as well as the difference between BIM and two-dimensional CAD technology, summarizes the realization method of BIM, the present situation of BIM development and some obstacles in our country. (2) aiming at the complex structure of bridge engineering construction, This paper studies the construction technology and management method based on BIM in bridge construction by combining with the basic characteristics of BIM technology and the problems caused by the complex construction environment and the "extensive" management mode. Through research and analysis, it is found that BIM technology can effectively improve the construction technology and management level of bridge engineering, improve the construction efficiency to a certain extent, and make the management more precise. To some extent, some problems in bridge construction are solved. (3) aiming at the BIM model of Nielsen system tied arch bridge, the software of Autodesk Revit and Bentley is used. Finally, Bentley is chosen as the BIM software of Nielsen system tied arch bridge. The structure model, arch support model and site model of tied arch bridge are established. (4) with the help of Bentley software and the completed model, the construction scheme of tied-arch bridge with Nielsen system is designed. Site simulation, 4D schedule simulation and digital construction are applied to realize the application of BIM technology in construction. The research results are helpful to the application research of other similar projects in the industry and can play a certain reference role in the construction examples of other projects.
