Abstract: It’s inevitable to disturb strata, leading to strata deformation in different degree, in the urban metro shallow tunnel excavation. It can influence the safety of subway construction and environment. In the paper, based on the analysis of the temporal-spatial effects of surface settlement and its mechanism caused by the construction of the shallow tunnel, analyze the 1400 ground surface settlements of 24 running tunnels in Beijing subway Line 5 and Line 10 with the fuzzy cluster analysis method. The general distinction of ground surface settlement and its distribution during construction of shallow tunnel is represented. What’s more, ground settlement trough width parameter inflexion point distance is represented, too. Stratum loss ratio of is gained. The relation between ground settlement slot width parameter inflexion point distance and equivalence axial burial depth has been set up.
