Model Tests on the Stability of RetainingWalls with Gabions Under Earthquake and Rainfall Conditions

In this study, based on the damage survey in Nepal, shake table tests and rainfall experiments using a typical gabion retaining wall model were conducted to investigate the influence on earthquake and rainfall basically. In a series of experiments, two same models with retaining wall with slope ground same as typical gabion retaining wall in Nepal were constructed in rigid soil container. Then, the model experiments containing shake table test after preceding rainfall and rainfall after preceding shake table test were simultaneously performed in order to confirm difference of the damage aspects caused by pattern of earthquake and rainfall. As main results, itwas confirmed that the deformation tendency of the gabion retaining wall was different by the order of rainfall and earthquake. Especially, the deformation of the retaining wall in Case of preceding shake table test was minor compared to preceding rainfall. Regardless of the order by rainfall and earthquake, the gabion retaining wall showed the same tendency on deformation mode.
