摘要
盾构机施工引起的土地变形无法避免,若控制不当可能对地上或周围建筑造成严重损害,铁路站场线对沉降变形控制要求严格,因此,盾构下穿铁路站时的施工难度较大。对盾构下穿铁路站场不良地基施工关键技术进行了研究,报告了盾构下穿铁路站不良地基施工时的地基加固及盾构施工关键技术。
The land deformation caused by shield construction is unavoidable, and it may cause serious damage to the ground or surrounding buildings if it is not properly controlled. The railway station and yard line has strict requirements on settlement deformation control, so the construction of shield tunneling under railway station is quite difficult. In the paper, the key technologies of shield undercrossing railway station bad foundation construction are studied, and the foundation reinforcement and key technologies of shield undercrossing railway station bad foundation construction are reported.
