北京地铁14号线技术创新综述

北京地铁14号线是北京市轨道交通网络中的一条L型大运量级骨干线,汲取国内外城市轨道交通建设的成熟经验,贯彻安全、环保、节能、绿色、人文等理念,在工程设计、施工、机电设备集成及安装、安全、环保、节能等领域进行诸多创新。因地制宜设计大中庭同步开发物业车站、大直径盾构扩挖车站、洞柱法暗挖3层结构形式的车站等多种车站建筑空间形态,开发深基坑连续墙施工、盾构机站内平移接收、既有线上方转体箱梁合龙等施工新工法工艺,为国内地铁设计与施工提供良好的技术储备。

Technical Innovations in Beijing Metro Line 14

Beijing Rail Transit Line 14 is an L-shaped large-capacity trunk line in Beijing''s rail transit network. Drawing on the mature experience of urban rail transit construction both domestically and abroad, Beijing Rail Transit Line 14 implements the concepts of safety, environmental protection, energy saving, green technologies, and public good based on many different innovations in engineering design, construction, mechanical and electrical equipment integration and installation, safety, environmental protection, energy saving, and other areas. According to the local conditions, a large-space courtyard design with the synchronous development of a property station, a large-diameter shield-dug station, a three-story structure of a tunnel excavation station and other stations with different building shapes, a deep foundation pit developed with the construction of a continuous wall, a shield machine station, translation and reception services, the existing line above the box girder closure, and other new construction methods for a domestic subway design and construction provide a good technical reference.
