【摘要】：随着人们对BIM技术不断地研究和深入,越来越多的桥梁设计师将BIM技术与桥梁项目工程相结合。在两者相互融合的过程中,它们之间的优势以及短板将会显现出来。本论文主要通过以下几个方面来具体阐述基于BIM的桥梁工程设计与应用:(1)通过查阅国内外相关文献,查找BIM的起源,并归纳总结出BIM的优势。另外,调查BIM在美国、英国、韩国等BIM发达国家的应用状况和未来发展趋势。调查并分析BIM在中国发展的状况以及相关政策。之后介绍了几款主流BIM核心软件;(2)结合相关的BIM核心软件,说明BIM技术是如何在桥梁项目工程的规划阶段进行选线、方案比选;在设计阶段进行二维出图、工程量计算;在施工阶段进行施工模拟以及在运维阶段进行桥梁养护等应用,并且总结出了BIM的可出图性、信息化、协同性、可视化等几大特性;(3)结合蝴蝶型拱桥实例,使用BIM核心建模软件CATIA对蝴蝶型拱桥进行三维信息模型的建造。归纳总结出在CATIA软件中建立桥梁模型的原则、“骨架+模板”的建模方法和建模注意事项等内容,并详细说明了如何使用三维模型的碰撞检查、精确工程量的计算、二维平面出图等功能;(4)结合桥梁有限元分析软件Midas Civil对蝴蝶型拱桥进行整体的强度和稳定性的验算。探究了拱肋刚度、拱肋轴线与铅直平面的角度以及荷载工况对桥梁整体稳定性的影响;(5)探索了如何利用BIM平台对桥梁项目工程进行运营和维护的管理,并基于蝴蝶型拱桥建筑信息模型搭建了桥梁管理系统。同时,为了使桥梁巡查养护更加快捷化和信息化,制作了桥梁巡查养护应用。能够随时随地的查看桥梁相关安全信息和记录、上传桥梁安全情况。最后,根据BIM技术在蝴蝶型拱桥设计和应用中出现的问题,提出BIM技术在桥梁项目工程中需要改进之处。
[Abstract]:With the continuous research and in-depth study of BIM technology, more and more bridge designers combine BIM technology with bridge project engineering. In the process of fusion, their advantages and weaknesses will be revealed. This paper mainly describes the bridge engineering design and application based on BIM through the following aspects: (1) through consulting the relevant literature at home and abroad, looking for the origin of BIM, and summing up the advantages of BIM. In addition, the application and future trend of BIM in BIM developed countries such as USA, UK, Korea and so on are investigated. Investigate and analyze the development of BIM in China and related policies. Secondly, several mainstream BIM core software are introduced. (2) combining with the related BIM core software, the paper explains how to select the line and plan in the planning stage of bridge project, how to draw out the two-dimensional drawing in the design phase, and how to calculate the engineering quantity, and how to select the line and plan in the planning phase of the bridge project. The application of construction simulation in construction phase and bridge maintenance in operation and maintenance stage are also summarized, and several characteristics of BIM, such as drawing, informatization, collaboration, visualization, etc., are summarized. (3) combined with the example of butterfly arch bridge, the three-dimensional information model of butterfly arch bridge is constructed by using BIM core modeling software CATIA. This paper summarizes the principle of building bridge model in CATIA software, the modeling method of "skeleton template" and the points for attention in modeling, and explains in detail how to use the collision check of three-dimensional model and the calculation of accurate engineering quantity, and so on. Two-dimensional plane drawing and other functions; (4) the overall strength and stability of butterfly arch bridge are checked by the finite element analysis software Midas Civil. The stiffness of arch rib, the angle of arch rib axis and vertical plane and the influence of load condition on the overall stability of bridge are discussed. (5) how to use BIM platform to manage the operation and maintenance of bridge project is explored, and the bridge management system is built based on the information model of butterfly arch bridge. At the same time, in order to make bridge inspection and maintenance faster and more information, the application of bridge inspection and maintenance was made. Can view bridge-related safety information and records anytime and anywhere, upload bridge safety situation. Finally, according to the problems of BIM technology in the design and application of butterfly arch bridge, the improvement of BIM technology in bridge project is put forward.
