【摘要】：随着人类文明的不断进步和科技的迅猛飞跃,我国交通事业也不断迈向新的高度,在大河、大江甚至海湾之上架桥已经变得越来越普遍。在经济发展面前,提高运输效率等因素促进了预应力混凝土连续梁桥的发展。目前国内、外的连续梁桥一般采用悬臂浇筑施工的办法。为了确保桥梁的强度、刚度和耐久性满足规范要求,确保连续梁能够达到预期的工程质量,全桥的施工监控、0#块托架设计及挂篮计算是必须要考虑的。论文从说明一般的预应力混凝土连续箱梁施工方法出发,从设计角度详细分析了黄坊溪3#大桥的特点。主要介绍了桥梁概况、设计采用的技术标准、技术条件、主要材料、箱梁结构设计、施工要点等。通过设计分析,为施工方案的制定提供了基础。通过实际工程中出现的问题,研究连续梁施工的关键技术,提出合理的解决方案。借此对类似工程施工技术提供良好的借鉴作用。最后,通过对本工程施工全过程的分析,提出了一些自己的体会。
[Abstract]:With the continuous progress of human civilization and the rapid leap of science and technology, China's transportation industry is constantly moving to a new height, in the river, river or even the Gulf over the bridge has become more and more common. In the face of economic development, improving transportation efficiency and other factors promote the development of prestressed concrete continuous beam bridge. At present, the cantilever pouring method is generally used in the continuous beam bridges. In order to ensure that the strength, stiffness and durability of the bridge meet the requirements of the code, and ensure that the continuous beam can achieve the expected engineering quality, the design of the block bracket and the calculation of the hanging basket of the whole bridge construction monitoring block must be considered. Based on the general construction method of prestressed concrete continuous box girder, this paper analyzes the characteristics of Huangfang Xi3# Bridge in detail from the point of view of design. This paper mainly introduces the general situation of the bridge, the technical standard, the technical conditions, the main materials, the structural design of the box girder, the key points of construction and so on. Through the design analysis, provides the foundation for the construction plan formulation. The key technology of continuous beam construction is studied through the problems in practical engineering, and a reasonable solution is put forward. This provides a good reference for similar engineering construction technology. Finally, through the analysis of the whole construction process of the project, some experiences are put forward.
