由于吹填土地层的特殊性,在泥水盾构穿越吹填土过程中对地层易产生较大的扰动,从而会引起较大的地层变形。结合上海轨道交通11号线南段的工程实例,对此工程中不同施工工况条件下地表沉降横断面的实测数据的变化规律进行分析研究,进而提出泥水盾构穿越吹填土的施工控制措施,对类似工程具有重要参考价值。 Due to the particularity of the dredger fill formation, it is easy to cause large disturbance to the formation during the process of mud shield tunneling through the dredger fill, which will cause larger formation deformation. Combined with the engineering example of the south section of Shanghai Metro Line 11, this paper analyzes the changing law of the measured data of the surface subsidence under different construction conditions, and then puts forward the construction control measures of the slurry shield through the dredger fill , For similar projects have important reference value.
