Abstract: Long-term and excessive extraction of groundwater has led to serious regional land subsidence in Shanghai.

Using field data obtained from extensometer groups and observation wells, the changes in groundwater levels in aquifer units and the characteristics of soil deformation were analyzed for the period 2001–2012. The water level in the phreatic aquifer and the first confined aquifer remained approximately stable, while the water level in the second to fifth confined aquifers followed an obvious rising trend over the study period. Moreover, three soft layers remained under compression, but the deformation of the third soft layer was effectively controlled and rebound occurred in some areas. Under the condition of overall recovery of groundwater, the first to fourth confined aquifers showed clear plastic and creep deformation. The deformation of the aquifer sand lags behind the variation in the water level. With the groundwater level rising continuously, the soil layer was still compacting, while the fifth confined aquifer behaved primarily as an elastic material, and the sand layer rebounded constantly, although the lag was not as obvious. Four modes were classified based on the relationship between the deformation and the groundwater level of the aquifer under the pumping conditions between 2001 and 2012. The results of the laboratory creep test showed that the newly developed double-yielding viscoelastic-plastic model is able to simulate the deformation characteristics of saturated sand.

Key words: land subsidence; control of groundwater extraction; sand creep; deformation characteristic; constitutive model
