    Abstract:

    In order to recognize the regularity and differences in the selection and design of the mud pump type for the slurry shield, in view of the shortcomings of the existing research, the statistical analysis method is adopted to analyze the 17 key parameters with regard to 15 field cases, including the diameter of the excavation, the length of the tunnel, the main stratum, pipe diameter, density and flow of inlet and discharge mud. Six conclusions are obtained, such as the first-order linear regression equation between the pipe diameter, density and excavation diameter of inlet and discharge mud, the selection rule of inlet and discharge mud density for different formation; and they have been successfully applied to the ventilation shaft slurry shield section between Binhai Xincheng Station and Airport Station on F1 Line of Fuzhou Metro. The research results can provide new ideas for the selection or evaluation of mud pumps in the future.
