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

Abstract

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, it was 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.

Effect of the Wall‐Back Inclination Angle on the Inertial Loading Distribution along Gravity‐Retaining Walls: An Experimental Study on the Shaking Table Test

“…Te shaking table test of retaining walls began in the 1970s [12,13]. In recent years, shaking table model experiments have been widely used to study the dynamic response of gravityretaining walls [8,[14][15][16][17][18][19] and other types of retaining walls (such as cantilever-retaining walls [20], geosyntheticreinforced soil-retaining walls [21,22], soil bag-retaining walls [23], geogrid-reinforced retaining walls [24], and reinforced retaining walls by anchored piles [1]). However, the shaking table test of gravity-retaining walls is mostly about dynamic lateral earth pressure or stability of retaining walls, and there are few studies on the ψ i of gravity-retaining walls.…”
