摘要
结合南京火车站站前广场龙蟠路隧道(南侧)西段上跨已建成的地铁1号线双线盾构隧道时的基坑支护工程,采用排桩与桩板支护法有效地解决了基坑开挖中盾构隧道隆起位移控制的难题。并就箱形隧道基坑下已建地铁盾构隧道隆起位移的控制分析计算、排桩与桩板支护设计及施工方法、施工中的位移监控量测结果作了较详细地分析论述。
The protection of two existed tunnels which are right under the Longpan tunnel’s excavation located in Nanjing Railway Station’s Square is presented. Due to the combining use of piles retaining and strips of excavation, the existed shield tunnel’s upwarping during the excavation is controlled successfully. The analysis and calculation of existed tunnel’s upwarping, the piles retaining’s design and the deformation’s supervision during the construction are also analyzed in detail. This excavation made a good ...
