| 摘 要： | 广州地铁六号线东山口站为国内首例在周边环境复杂条件下实施"先隧后站、盾构隧道扩挖"修建地铁车站的工程。文章介绍了该站左线站台隧道在盾构隧道的基础上扩挖形成地铁车站的主要修建技术及施工特点和难点。实践证明,采用盾构与明(暗)挖法相结合修建地铁车站的施工技术,是城市繁华地区修建地铁车站有效解决区间盾构隧道与车站施工相互干扰难题的重要途径。

| Abstract: | The Dongshankou station of the Guangzhou Metro line 6 has been built featuring the "tunnel going first" and subsequent "expanded excavation by shield." This article introduces the construction techniques,characteristics,and difficulties of constructing the metro station based on the expanded excavation of the station platform tunnel after the running tunnel had been excavated through the station area.This practice indicated that the combination of shield and cutting(bored) excavation was one of the key means to solving the conflicts between running tunnels and station construction in urban areas. |
