| Abstract: | The main structure of high pressure consolidation apparatus and the modeling test method developed by authors are briefly introduced in this paper.According to the data obtained by modeling test,the basic properties of the compaction and dilation of the soil skeleton due to pumping and recharge are minutely analyzed .The constitutive function expressions of the stress-strain relationship of soils with viscoelasticity are determined,which are suitable for explaining the compaction mechanism of the skeleton in aquifer(s)caused by pumping and of the dilation (rebound)mechanism resulting from recharging. |
