摘要
以北京地铁十号线熊猫环岛—安定路区间工程为例,着重介绍隧道下穿密集商用建筑群、隧道立体交叉开挖、上层滞水丰富及新近规划在建的电力隧道造成建筑物严重损坏(经有资质单位鉴定)等复杂环境下采取的施工技术措施,通过管井降水、洞内水平井点真空降水、对建筑物段超前处理、隧道超前开挖、支护等措施成功地解决了以上难题,以期能为今后类似工程提供参考与借鉴。
Taking the construction of Xiongmao Huandao-Anding Road Tunnel on No. 10 line of Beijing Metro as an example, the authors mainly introduce the construction technology adopted in complicated conditions, such as tunnelling under commercial buildings, excavation under existing tunnels, tunnelling in water-rich ground and near electricity tunnel. The above difficulties have been successfully solved by pipe well dewatering, vacuum dewatering, advance treatment of the buildings and pre-support of the tunnel. This paper can provide reference for similar projects in the future
