Structural Sand Dynamic Elastic-Plastic Deformation Time-Dimensional Model
Dynamic shear characters of sands of Nanjing, Guangzhou, Harbin are studied, Some dynamic characters of schistose grain, shaft grain and round grain sand are compared and researched. The elastic-plastic change of structural sand skeleton under dynamic shear, the finally and irreversible deformation in the touched part of particle which maybe to produced elastic-plastic change deformation, the change of percent of mass different size particle, have been tested and he affection on dynamic shear from structures of schistose grain sand, staff grain and round grain sand and these affection to shear mould and extra-pore-pressure are analyzed. in order to simulate the nonlinear of dynamic volume and shear stress –shear strain during the liquefaction, a time-dimension-discrete model of sand diliatancy is suggested, the simplified equation can easy to explain the liquefaction and easily to analysis the dynamical deformations of soil.
