| 中文摘要:为了认清在泥水盾构泥浆泵选型设计时的规律性和差异性，针对现有研究的不足，采用统计分析法，从15个实际工程案例入手，统计了包括开挖直径、隧道长度、穿越主要地层、进排泥的管径、密度和流量在内的17个关键参数，分析在选型设计阶段关键参数之间的规律性和差异性，得到了进排泥的管径、密度与开挖直径的一次线性回归方程，不同地层的进排泥密度选取规律等6点结论，最后将结论成功运用于福州地铁F1线滨海新城站—机场站中间风井泥水盾构区间，研究成果可为今后泥浆泵选型或评估提供新的思路。 |

| 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. |
