摘要
文章结合深圳地铁2号线大剧院站至湖贝站上下重叠小净距盾构区间隧道工程实例,针对重叠盾构隧道的施工关键问题,进行了受力分析,提出下洞采取钢管支撑的施工技术措施,并通过实测进行了验证,为后续项目提供了经验。
Considering the shield-driven overlapped running tunnels with small clear distance from Grand Theater B Station to Hubei Station of Shenzhen Metro Line 2,stress analysis was carried out in view of the key problems in the case of overlapped shield tunnels.Steel pipe support for the lower tube was adopted and checked by the in-situ measurement.
