| 摘 要： | 在城市地下进行盾构施工,不可避免要穿越建筑物。以苏州市轨道交通2号线为例,通过对盾构在饱水粉砂层以小半径曲线穿越建筑群采用的土仓压力、出土量、泡沫剂、监控数据等参数的分析和探讨,研究和总结了苏州地铁盾构在粉砂层穿越建筑群采用的技术措施,希望对同类工程施工提供借鉴。

| Abstract: | In the construction of underground shield tunneling, sometimes shielding will inevitably cross the buildings. Taking the Suzhou Metro Line 2 as an example, through analysis and discussion of soil pressure, the excavation volume, foams, monitoring data and other parameters used in small radius curve crossing buildings in saturated silt strata, this paper studies and summarizes the technical measures used in Suzhou Metro shield through the buildings in silt layer, hoping to provide a reference for similar projects. |
