摘　　要：提出了软土地层中盾构穿越建(构)筑物群的变形控制关键技术,从导致盾构周围地表及建(构)筑物变形的诱因出发,引进灰色关联分析理论,对不同工况计算了磁浮结构设施变形量与施工参数间的关联度和关联度排序,进而可通过重点调节敏感度较高的施工参数来有效控制变形,保证工程安全。In this paper, the key technology of deformation control for shield tunneling through building group in soft soil layer is put forward.The grey correlation analysis theory is introduced from the inducement of the deformation of ground surface and building(building) around shield. The degree of correlation and ranking between the deformation of maglev structure and construction parameters are calculated under different working conditions, and the deformation can be effectively controlled by adjusting the construction parameters with high sensitivity, so as to ensure the safety of the project.
