Measured deformation of dredger fill during slurry shield tunneling

Due to the particularity of dredger fill, slurry shield tunneling will cause large ground deformations during undercrossing dredger fill. Based on a practical example of Shanghai Metro line 11, the transverse variation curves of ground settlement under different construction conditions are analyzed. Some construction control measures are proposed for the slurry shield undercrossing dredger fill. This study may serve as reference for the similar projects．
