Since　the　existing　model　boxes　cannot　meet　requirements　in　shaking　table　model　tests　of　complex　underground　structures＇　seismic　response　under　two-dimensional　horizontal　earthquake　shaking.　A　suspended　laminar　multidirectional　shear　model　box　has　been　developed.　Shaking　table　tests　were　carried　out　to　verify　the　performance　of　the　box　and　the　test　result　showed　that　shear　deformation　without　torsion　occurred　in　the　sand　specimen　under　the　shear　wave　action　induced　by　the　shaking　table.　The　suspended　laminar　multidirectional　shear　box　is　very　satisfactory　in　simulating　lateral　boundary　conditions　of　the　horizontal　prototype　soil　layers　and　can　be　used　in　the　shaking　table　model　tests　to　be　developed.
