Abstract: Shanghai subway tunnel crossing -1400mm water-supply line, through optimizing the cut pressure, driving speed, deviation, slurry quantity, dry sand content, synchronous grouting and secondary grouting quantity, pipe subsidence has be controlled at about 10 mm after shield crossing, this will be a reference for similar project.

Keywords: slurry shield; through the water-supply line; construction parameter
