摘　　要：介绍北京地铁磁器口站至崇文门站区间的施工方法和支护手段,采用有限元方法对区间地铁隧道主体结构进行施工全过程数值模拟,以了解地铁区间隧道施工过程中的应力、位移变化, 掌握施工过程中影响洞室稳定性的关键因素,采用相应技术措施以确保安全.The construction method and the design of supporting structure of Beijiang Metro between Ciqikou and Chongwenmen are introduced. By using finite element method(FEM)the numerical simulation of building the main strusture of partial underground tunnel is given. So as to know of the stress,displacement in the process of building an underground tunnel,command the key factors that affect the stability of hollows and then adopt relative measures to ensure safety.
