Dynamic characteristics of reinforced gabion walls subjected to horizontal seismic loading

Large model tests are conducted on reinforced gabion walls filled with red sandstone under horizontal seismic loading to investigate the dynamic response of walls.PVC-coated heavy galvanized of double twisted hexagonal wire mesh is used in the tests,and the cells of wire mesh specimens have a dimension of 80 mm×100 mm.Input seismic waves are ELCE_NS and HACHI_EW,and the peaks are 0.342g and 0.183g respectively.The horizontal acceleration,vertical acceleration,dynamic horizontal displacement,dynamic vertical displacement,and dynamic stress peaks response of the first layer,the third layer,the fifth layer of reinforced gabion walls are achieved in the model tests under different peaks of horizontal earthquake incentives.The reinforced gabion walls are proved to be excellent aseismatic structures by the structural analyses and aseismatic experiments.The test results provide a reasonal basis for the aseismatic design of reinforced gabion walls.
