Through the statistical analysis of the technical data which based on shield tunneling, comprehensively considering the information of water-rich sandy gravel stratum, such as the tunneling parameter of the slurry shield machine, slurry parameter, shield posture and stratum deformation mechanism information, the empirical formula of the main parameters of synchronized grouting technologies is determined while the slurry shield is tunneling in sandy gravel stratum. It can guide the similar project construction.
