Abstract：In order to study the deformation behavior of reinforced gabion retaining wall，model test is carried out. The cyclic loads with five frequencies(2，4，6，8， 10 Hz) and three amplitudes(40–80，50–100，60–120 kPa) are imposed. According to the test，the dynamic deformation behavior(both lateral and vertical deformations) of wall face，the main influential factors and their significance，and the deformation behavior of retaining wall when unloading are obtained. Test results show that：(1) the dynamic deformation is affected by amplitude of cyclic load，vibrations，filling ratio of gabion cage and so on，and not significantly affected by vibration frequency；(2) large lateral deformation occurs in the third，the fourth and the fifth layers of wall face；(3) with the increase of amplitude，vibration time to stable deformation increases，and the deformation also increases；(4) dynamic deformation increases during vibration quickly first and then tends to be slowly；and (5) the lateral deformation of the wall face shows almost no elastic recovery when unloading.
