Deformation behaviour of over-consolidated soil in a deep confined aquifer under multi-stage pore pressure changes in Shanghai, China.

Shanghai, a typical coastal soft-soil area, is characterised by thick soft layers with high compressibility and low permeability. Together with five confined aquifers, these layers form a complex multi-aquifer system. Historically, excessive deep groundwater extraction caused severe land subsidence. However, after year...
