摘要
以某上跨盾构隧道的基坑工程为实例,围绕盾构隧道可能产生的抗浮问题采取了相应的施工技术措施,阐述了"三轴搅拌桩满堂加固、基坑限时分条开挖、抗拔桩+压顶板平衡、水袋压重"的施工技术路线。工程实施效果良好,相关数据均达到预期目标,对类似工程具有一定的借鉴价值。
Taking one foundation pit construction project upper-cross a shield tunnel as an example, the corresponding technical construction measures has been taken concentrating on the possible anti-floating problem of shield tunnel. This paper mainly elaborated the construction technical routes, such as ＂overall reinforcement of triaxial mixing piles, time-limit sectional excavation of foundation pit, balance of uplift pile and coping, and water-bag ballasting＂. The effect of engineering implementation was excellent and overall relevant data reached the expected goal, which had certain reference value for similar projects.
