Short summary

These exists a new phenomenon with continuous deformation in the sandy aquifers in Shanghai. Sharp hydraulic gradient would be formed in the aquifer and shear stresses would develop. Cumulated shear stress is one of the main factors that contribute to deformation within an aquifer. Cosserat continuum mechanics can be applied to analyse the mechanism of confined aquifer deformation controlled by accumulated shear stress.
