摘要
由于地铁车站所处环境极其复杂,盖挖逆作法以其占地少、回填小,快速覆盖、缩短中断交通时间,低噪音、少粉尘,不扰民等诸多优点,被广泛用于地铁车站施工中.笔者介绍了地铁车站盖挖逆作法施工技术的工作机理及其发展历程,重点从盖挖逆作法的围护结构、中间支撑柱、土方开挖三方面施工技术进行研究.通过对大量关于地铁车站盖挖逆作法研究文献的统计,针对以上三方面,对其最新施工工艺进行总结,为相关施工技术研究的专家学者提供一个最新的研究动态,也可为其他工程建设人员提供技术支持.
Because the environment around a subway station is very complex,top-down inverse construction method,due to its less area occupation and backfill;fast coverage,the short time of interruption of traffic;low noise,less dust,not disturbing and many other advantages,is widely used in subway station construction.This paper firstly introduces the working mechanism and development history of the top-down inverse construction method of subway station,and then focus on the construction technology of the three aspects of the retaining structure,central pile-columns,and the excavation of the earth with a great deal of statistics of the research literature on top-down inverse construction method of subway station.It finally summarizes the latest construction technology of the expert scholars about the above-mentioned three aspects,provides a new research on the construction technology research and technical support to other engineering construction personnel.
