【摘要】：目前各地区在桥梁施工中,对施工承重体系的采用仍然以满堂支架为主,但随着施工技术工艺的发展和进步,采用贝雷梁或综合满堂支架和贝雷梁作为施工承重体系已成为一种趋势。但是目前贝雷梁的施工和使用仍处在发展初期,还没有系统的理论分析的支撑和工艺标准以及使用原则。本文针对桥梁施工中的承重结构,从地形适应能力、结构受力、安全性能、施工操作特点、经济性能等方面,对满堂支架和贝雷梁两种施工技术的特点进行了分析、归纳和比较,并结合苏州市静波桥施工的工程实例,利用MIDAS/Civil分析软件,进一步分析和验证了贝雷梁支撑体系在施工各工况的受力性能,最后对满堂支架和贝雷梁两种施工技术的经济性能做了分析比较,提出了两种支撑体系综合运用的原则。本项目的研究内容既有理论意义,又有工程实际应用价值,特别是大型常规桥梁的施工,从安全、质量、进度、成本控制上具有其借鉴作用。
[Abstract]:At present, in the construction of bridges in various regions, the construction load bearing system is still mainly used as full support, but with the development and progress of construction technology, It has become a trend to adopt Bei-ray beam or comprehensive full-hall support and belay beam as construction load-bearing system. However, the construction and use of Berelli beam is still in the early stage of development, there is no systematic theoretical analysis of the support and technical standards as well as the use of principles. Aiming at the load-bearing structure in bridge construction, this paper analyzes the characteristics of two construction technologies, such as terrain adaptability, structural stress, safety performance, construction operation characteristics, economic performance, etc. Combined with the engineering example of static wave bridge construction in Suzhou City, this paper further analyzes and verifies the mechanical performance of Beilai beam support system under various construction conditions by using MIDAS/Civil analysis software. At last, the economic performance of the two construction technologies is analyzed and compared, and the principles of comprehensive application of the two kinds of supporting systems are put forward. The research content of this project has both theoretical significance and practical application value, especially in the construction of large conventional bridges, from the safety, quality, schedule, cost control has its reference role.
