摘　　要：地铁工程常采用先站后隧的施工工序,本文提出了一种地铁车站与区间叠合同期施工的施工技术。将叠合法关键施工技术运用于北京地铁8号线三期工程土建施工03合同段的工程实践,采用数值计算和现场监测等手段评价了其施工效果,并提出了适用条件。相比传统的施工方法,叠合法施工具有施工周期短、环境适应性强等优点,对复杂条件下城市地铁建设具有一定的指导意义。The construction of subway projects often adopts the process of building stations before tunnels.This paper proposes a construction technology for overlapping construction periods of subway stations and intervals.The key construction technology of the overlay method was applied to the civil construction of Contract Section 03 of the Phase III project of Beijing Subway Line 8.Numerical calculations and on-site monitoring are employed to evaluate the construction effects and to propose applicable conditions.Compared with traditional construction methods,overlapping construction has advantages such as shorter construction periods and stronger environmental adaptability,providing certain guidance for urban subway construction under complex conditions.
