The train loading is simplified as equivalent rectangular cyclic loading in this paper to investigate the influence of train loading on long-term deformation of soft soil around a shield tunnel. Based on the empirical relation between permeability and compressibility, the governing equation of nonlinear consolidation is established. Then the analytical solutions are derived after the partially sealing lining as boundary condition is considered by introducing a dimensionless relative parameter of soil-lining permeability. The rationality of corresponding analytical solutions is confirmed by the comparison among predictions of ground settlement by presented solution and field data from Shanghai Metro Line No.1. The results show that the increment of ground settlement by train loading is positively correlated with partially sealing condition. The presented solutions provide a reasonable and effective tool for the prediction of long-term ground settlement by the operation of metro way.
