The objective of this study was to clarify the structural performance of different types of retaining walls. In this study, an experiment was conducted on the structural performance of the L-type retaining wall (L/H=0.6) and the lean-type gravity retaining wall with a gradient of 1:05 by applying varying uniformly distributed loads on the ground surface. This study has led to the following observations. (1) In the case of the L-type retaining wall (L/H=0.6), it is concluded that if the structural strength and the bearing capacity of the soil are high enough, the structural performance of the retaining wall is satisfactory until a uniformly distributed load equivalent to the weight of a layer of earth with a height about seven times that of the back-fill is applied on the ground surface. (2) In the case of the lean-type gravity retaining wall with a gradient of 1:05, it is concluded that if the structural strength and the bearing capacity of the soil are high enough, the structural performance of the retaining wall is satisfactory until a uniformly distributed load equivalent to the weight of a layer of earth with a height about 2.5 times that of the back-fill is placed on the ground surface.
