Abstract: The properties of gabion mesh Role properties are examined by the indoor pull-out test,the dynamic features of reinforced gabion retaining wall analysis are studied through shaking table test,analyzing the destruction under seismic loading and the failure law of its ground breaking pressure,to find out the worst part of reinforced gabion retaining wall under seismic loading and provide Related measures for enforcing the wall. Geo-Studio software,using an artificial coupling finite element numerical simulation model,compares analytically the results of shaking table model test and the finite element numerical simulation with the same size,to further study the dynamic characteristics of reinforced gabion retaining wall,study reinforced gabion retaining wall system in the overall force system gabion retaining wall and the wall reinforcement effects.

Key words: gabion retaining wall, gabion mesh, vibration table, finite element, numerical simulation
