TL;DR: A 16-18m deep excavation for a metro station with in-plane dimensions of approximately 20m wide by 290m long was constructed by using the cut-and-cover technique in soft clay in Shanghai metropolitan area, in which many high-rise buildings and utilities exist.

TL;DR: In this article, the characteristics of a large-scale circular excavation constructed by the bottom-up method in Shanghai soft clay were extensively investigated, including lateral wall deflections, vertical wall movements, lateral ground movements, ground settlements, subsurface settlements, vertical column movements, column stresses, and variation of pore pressures along depth and artesian water levels.

TL;DR: Wang et al. as discussed by the authors focused on the behavior of the peripheral pit via the following investigated items: (1) lateral wall deflections; (2) vertical wall movements; (3) lateral ground movements, (4) axial forces in the cast floor slabs and braced struts; (5) lateral earth pressures on both sides of retaining walls; (6) variation of pore pressures along depth and deep artesian water levels; (7) ground settlements; (8) subsurface settlements, (9) basal heaves; (10) vertical column

TL;DR: The construction of a subway station in Shanghai called for a 31.4-33.1m-deep excavation, which extended through upper impermeable clayey strata into underlying erodible silt and sand aquifer as discussed by the authors.

TL;DR: Wang et al. as discussed by the authors examined the performance of an oversized deep excavation in stiff clayey deposits and the corresponding responses of the adjacent metro station to adjacent excavations, in order to understand potential adverse effects of excavations on adjacent metro lines in service.
