Introduction It is very complex of sand dynamic irreversible deformation during earthquake, some time, the sand dynamic irreversible deformation or destroy has relationship with the structural dynamical characters of same typed structural sand, such as sands of Nanjing(YangTse River), Guangzhou(Zhujiang River), Harbin(Sunhuajiang River).The deformation can be divided into elastic deformation and-plastic deformation, in larger part of that is elastic dynamic response, another part of deformation is non-elastic dynamic respond, or it can be regarded as irreversible deformation, some this irreversible deformation can induced the sand engineering fail or destroy, at present, the model of sand irreversible deformation are always founded by tests or engineering, no research working having thought of sand different structure characters.
The dynamical shear characters of sand in engineering is very complex, among those for Earthquake problem , the type problem is seismic liquefaction, sand will produced plastic deformation under dynamical shear, these irreversible deformation will affected pore-water pressure development, to study non-linearly dynamical volume deformation is very useful to study the seismic liquefaction.
