【摘要】：随着我国经济实力的不断增强,生产力水平得到了快速的发展,信息化程度不断提高,深层次影响着社会各行各业。在桥梁工程领域,设计理念和结构形式越来越先进,传统行业粗放的管理模式,导致施工效率低下,阻碍着桥梁工程领域的进步和创新,正面临着多种方式的改进。BIM技术的出现能够很好地解决这一问题,BIM模型可以覆盖项目建设全生命周期的各个阶段,为桥梁从设计到与运营维护的不同阶段提供及时、完整和准确的信息,并为不同阶段的项目参与方提供信息交流和共享的平台,它以可视化、协调化和信息集成化为核心,贯穿桥梁工程的全生命周期,能够大幅度提高施工效率和建造质量。现行的土木工程行业尽管在规划、设计、施工和运维阶段,使用信息技术作为辅助工具,但是我国桥梁工程行业中BIM技术的应用目前还处在起步阶段,真正在桥梁全生命周期使用BIM技术集成的案例很少,项目参与方很多情况下只是听说过BIM技术,主要原因在于桥梁工程BIM核心建模软件的缺失、相关BIM规范标准尚未形成和BIM在桥梁施工中的应用案例较少。行业内需要进一步开展深入研究,利用BIM技术更好地为我国桥梁工程事业服务。本文以郑万铁路128m尼尔森体系系杆拱桥系梁施工为工程背景,主要研究系梁建造过程钢管立柱-贝雷梁支架系统施工中的BIM技术应用,结合设计图纸和专项施工方案,完成基础支架体系的BIM模型创建,将BIM技术应用到系梁支架施工全过程中,开展了以下几个方面的研究工作:(1)本文从建筑信息模型(BIM)定义出发,介绍了BIM技术国内外发展现状,并对BIM核心建模软件和IFC技术标准进行了介绍,明确了选取的建模软件和研究方向。(2)通过BIM技术在桥梁工程设计阶段、施工阶段和运维管理阶段应用的功能不同,说明BIM技术能够有效地解决传统技术层面无法解决的问题,极大地提高了设计质量和施工效率,为施工单位带来了可观的经济效益和社会效益。(3)研究基于Bentley Pro Structure郑万铁路128m尼尔森体系系杆拱桥系梁施工过程中钢管立柱-贝雷梁支架系统的建模方法,创建了128m系杆拱桥系梁支架施工参数化构件族库,可为同类桥型BIM建模提供BIM模型组件。(4)研究分析了BIM技术在郑万铁路128m尼尔森体系系杆拱桥系梁支架施工过程中3D出图、碰撞检测、材料统计和4D进度模拟等功能的应用实践,验证了BIM技术在郑万铁路128m尼尔森体系系杆拱桥施工过程中与实际结合应用是可行的。本文建立的BIM模型为施工单位的现场施工组织提供了强有力的技术保障,提高了现场信息化管理水平,极大地提高了施工管理效率。
[Abstract]:With the increasing of our country's economic strength, the level of productivity has been developed rapidly, the level of informatization has been improved constantly, and it has deeply influenced all kinds of social industries. In the field of bridge engineering, the design ideas and structural forms are becoming more and more advanced. The extensive management mode of the traditional industry leads to low construction efficiency and hinders the progress and innovation in the field of bridge engineering. The BIM model can cover all stages of the whole life cycle of the project construction and provide timely for the bridge from design to operation and maintenance. Complete and accurate information, and a platform for information exchange and sharing for project participants at different stages, with visualization, coordination and information integration at its core, throughout the life cycle of bridge engineering, The current civil engineering industry, despite its use of information technology as an auxiliary tool during the planning, design, construction and operational phases, can significantly improve the efficiency and quality of construction. However, the application of BIM technology in the bridge engineering industry in China is still in its infancy at present. There are few cases of using BIM technology integration in the whole bridge life cycle. The project participants have only heard of BIM technology in many cases. The main reasons are the lack of core modeling software of BIM in bridge engineering, the unformed standard of relevant BIM specification and the few cases of application of BIM in bridge construction. Using BIM technology to serve the bridge engineering in our country better. This paper takes the construction of tied arch bridge with 128m Nielsen system in Zhengwan railway as the engineering background. This paper mainly studies the application of BIM technology in the construction of steel pipe vertical column-Beere beam support system during the construction process of tie beam. Combined with the design drawings and the special construction scheme, the BIM model of the foundation support system is created. This paper introduces the development of BIM technology at home and abroad, starting from the definition of building information model (BIM1), applying BIM technology to the whole construction process of tie beam support, and carrying out the research work in the following aspects: (1) in this paper, we introduce the development of BIM technology at home and abroad from the definition of building information model. The core modeling software of BIM and the technical standard of IFC are introduced. It is clear that the selected modeling software and research direction. The application of BIM technology in bridge engineering design stage, construction stage and operation and maintenance management stage is different. It shows that BIM technology can effectively solve the problems that cannot be solved by traditional technology, and greatly improve the design quality and construction efficiency. It has brought considerable economic and social benefits to the construction unit.) based on Bentley Pro Structure, the modeling method of the steel pipe vertical column and belay beam support system in the construction process of the tied arch bridge with 128m Nielsen system based on the Bentley Pro Structure is studied. The parameterized member family library of 128m tied arch bridge is established, which can provide BIM model module for similar bridge BIM modeling. The 3D drawing of BIM technology in the construction process of tied arch bridge with 128m Nielsen system in Zhengwan-Wan railway is analyzed. The application of collision detection, material statistics and 4D schedule simulation, It is verified that the application of BIM technology in the construction of 128m Nielsen system tied arch bridge is feasible. The BIM model established in this paper provides a strong technical guarantee for the construction organization of the construction unit. Improve the level of field information management, greatly improve the efficiency of construction management.
