【摘要】：随着城镇现代化的不断发展以及公路等基础设施的建设,建筑物整体位移工程的规模和数量都在不断快速增长,建筑物整体移位技术也随着大量工程实践而不断发展,这种新技术的应用成功解决了城市改造和道路规划过程中的诸多问题,具有良好的社会效益和经济效益,有着宽广的工程应用前景,并且能够有效的保护重要的历史建筑,延续其历史文化价值。但是建筑物整体移位技术尚没有形成完整的设计理论,在理论研究方面远远落后于实践。本文引进了一种新型的平移技术--高压气囊搬运技术,该技术是随着港口建设的发展而逐步演变出来的,通常用于船体和沉箱的平移和出运等,应用于地面建筑物的平移尚属首例。结合山西省临汾市襄汾县的大吨位“锣鼓之乡”雕塑平移工程,采用MIDAS软件对气囊托换前后的筏板及墙体进行受力分析,并对工程中现场采取的数据进行处理及分析。经过分析印证了本次平移工程的施工过程是安全可靠、平稳有序的。根据平移的建筑物特点及高压气囊搬运技术的工法特点,总结了施工过程中关键技术,为其他类似工程提供了参考。
[Abstract]:With the continuous development of urban modernization and the construction of infrastructure such as roads, the scale and quantity of the overall displacement engineering of buildings are increasing rapidly. With the development of a large number of engineering practices, the application of this new technology has successfully solved many problems in the process of urban transformation and road planning, and has good social and economic benefits. Has broad engineering application prospects, and can effectively protect important historical buildings, continue its historical and cultural value, but the overall displacement of the building technology has not formed a complete design theory. This paper introduces a new type of translation technology, high pressure airbag handling technology, which evolves with the development of port construction. It is usually used for the translation and transportation of the hull and caisson, and is the first case to be applied to the translation of the ground buildings. Combined with the large tonnage "township of gongs and drums" sculpture translation project in Xiangfen County, Linfen City, Shanxi Province. The force analysis of raft and wall before and after air bag underpinning was carried out by MIDAS software. And the data taken in the site of the project are processed and analyzed. The analysis proves that the construction process of the translation project is safe and reliable. According to the characteristics of the translational building and the working method of the high-pressure airbag handling technology, the key technology in the construction process is summarized, which provides a reference for other similar projects.
