Abstract
A strip-membrane type laminar box for shaking table test was developed which enabled liquefied and laterally spreading soils to reproduce large shear deformation. The laminar box reproduced residual shear deformation after soil liquefaction and large shear deformation over 10% during lateral spreading. Relation between shear stress and shear strain obtained from shaking table test using the laminar box made examination into the detail possible to concerning cyclic mobility phenomenon as well as soil liquefaction.
