In the model test, the same two retaining wall models with slope model grounds behind the retaining wall models were constructed in rigid soil container. Then, the model tests containing shake table test after preceding rainfall and rainfall test after shaking were simultaneously performed to confirm difference of the damage aspects caused by these patterns. The same tendency on deformation mode of gabion retaining wall was confirmed regardless of the order by rainfall and earthquake. As for the collapse of the retaining wall, though the concrete retaining wall collapsed suddenly during shaking, the gabion retaining wall collapsed after shaking for a while in case of shake test after the preceding rainfall, and exhibited so-called tenacity.
