【摘要】：近些年来,我国建造了一大批世界级桥梁,在桥梁基础设施建设领域取得了巨大的成就。目前,桥梁结构设计愈加追求新颖与构造复杂化,施工技术难度越来越大,建造参与方众多,因此不可避免的会造成设计、施工、管理、协同工作不能成为一个统一整体等问题,目前解决该问题的有效途径之一就是BIM技术的引入与工程实践。BIM技术这些年随着国家的大力推广,已取得了一定的成果。论文首先对BIM技术及BrIM技术作了简介,随后介绍了BIM技术在美国、新加坡、英国的发展及规划,同时分析了国内BIM技术的应用现状。本论文BIM技术的详细应用依托于郑万铁路128m尼尔森体系下承式系杆拱桥建造工程,利用Bentley系列软件,如PowerCivil、Navigator、ProStructure等,结合施工现场实际,通过应用BIM技术成功地提前发现了内外吊杆之间碰撞、预埋钢管与预应力管道之间碰撞的问题,避免了施工事故的发生。应用三维可视化技术进行现场施工技术交底、振捣方案的优化。还实现了工程量的统计、渲染漫游视频的生成。并尝试着实现了部分BIM施工信息管理、BIM施工进度管理的功能。最后将BIM模型导出至Midas FEA、Ansys有限元软件中进行精细化有限元力学分析,大大节省了重复建立有限元模型的繁重工作,实现了郑万铁路128m尼尔森体系系杆拱桥建造过程三维可视化与有限元仿真分析功能的转换。本文实现了128m尼尔森体系系杆拱桥建造过程BIM技术的应用,成功的指导了现场施工,提高了现场施工管理的信息化水平,避免了过程施工的发生,事实证明:BIM技术有其自身巨大的优势,在国外发达国家已有了一套完善的体系,也有了大量的工程实际应用案例。在国内,桥梁建造全过程应用BIM技术还刚刚起步,对BIM的概念,BIM的标准、BIM的实施模式还都处于学习和摸索阶段。展望未来,随着国家相关部门的大力推广,未来越来越多的桥梁建造项目将使用BIM技术,相信BIM技术在大跨度复杂桥梁的建造过程会发挥越来越重要的作用,桥梁BIM技术有着广阔的应用前景。
[Abstract]:In recent years, China has built a large number of world-class bridges and made great achievements in the field of bridge infrastructure construction. At present, the bridge structure design is becoming more and more novel and complicated, the construction technology is becoming more and more difficult, the construction participants are numerous, so it will inevitably lead to design, construction, management, Cooperative work can not become a unified whole and so on. One of the effective ways to solve this problem is the introduction of BIM technology and engineering practice. This paper first introduces BIM and BrIM technology, then introduces the development and planning of BIM technology in the United States, Singapore and Britain. At the same time, it analyzes the application status of BIM technology in China. The detailed application of BIM technology in this paper is based on the construction project of the through tie arch bridge in the 128m Nielsen system of Zhengwan railway. The application of Bentley series software, such as PowerCivil Navigator process, etc., is combined with the actual construction site. Through the application of BIM technology, the collision between the inner and outer suspenders and the collision between the pre-buried steel pipe and the prestressed pipe has been successfully discovered in advance, and the construction accident has been avoided. Three-dimensional visualization technology is used to optimize the site construction technology and vibration-tamping scheme. Also realized the project quantity statistics, the rendering roaming video generation. And try to realize part of BIM construction information management and BIM construction schedule management function. Finally, the BIM model is derived to the Midas FEA ANSYS finite element software for fine finite element mechanics analysis, which greatly saves the heavy work of repeatedly establishing the finite element model. The functions of 3D visualization and finite element simulation analysis for the construction process of 128m Nielsen system tied arch bridge in Zhengwan railway are realized. In this paper, the application of BIM technology in the construction process of 128m Nielsen system tied arch bridge has been realized, which has successfully guided the field construction, improved the information level of the site construction management, and avoided the occurrence of the process construction. It has been proved that the BIM technology has its own great advantages and has a set of perfect systems in developed countries and a large number of practical engineering cases. In China, the application of BIM technology in the whole process of bridge construction is still in its infancy, and the implementation mode of the concept of BIM is still in the stage of learning and groping. Looking forward to the future, with the vigorous promotion of relevant national departments, more and more bridge construction projects will use BIM technology in the future. It is believed that BIM technology will play an increasingly important role in the construction process of long-span and complex bridges. Bridge BIM technology has a broad application prospect.
