以暗挖施工北京地铁14号线朝阳公园站端头厅为研究对象,通过对暗挖施工端头厅车站单层结构的多种技术进行分析和比选,结合各种施工技术特点,形成了墙、梁、拱支撑框架体系构成的单层四导洞WBA施工技术。本工程应用此方法施工,有效控制施工引起的沉降,结构安全、质量合格,大大提高了施工效率;同时避免了大部分管线的改移,节约了管线改移的成本,减少施工对环境的影响,为地铁车站端头厅暗挖施工以及类似工程施工提供了实践经验。
Taking the construction of the terminal hall of Chaoyang Park Station of Beijing Subway Line 14 as a research object, by analyzing and comparing various technologies of the single-story structure at the terminal hall of the undercut construction and combining with the characteristics of various construction technologies, WBA Construction Technology of Single - layer Four - guide Tunnel Constructed by Wall, Beam and Arch Support Frame System. The construction of this project can effectively control the settlement caused by the construction, ensure the safety of the structure, ensure the quality and improve the construction efficiency greatly. At the same time, it avoids the shift of most of the pipelines, saves the cost of pipeline transfer and reduces the impact of the construction on the environment , Which provided practical experience for under-excavation construction of the subway station terminal hall and the construction of similar projects.
