Compared with round sand , dynamic shear mould and extra-pore-pressure of different structural sands, such as schistose,staff grain sand and other non-regular grain sand, are analyzed. The critical shear strain to induce extra-pore-pressure is suggested as a important and effective variable to study structural sands, Referring the dynamic shear dilatancy deformation model of round grain sand, some coefficients of time-dimension-discrete sand dynamic dilatancy model and parameters of elastic-plastic deformation constitutive model are suggested to think of sand structural characters. A simplified dynamic shear deformation equation for typical structural sand is suggested to analyze earthquake engineering problems.
