It is the purpose of this paper to point out that the reinforcement of retaining structure is affected by the stiffness of geotextiles. Model loading tests were carried out to investigate the bahavior of embankments reinforced by geotextiles with 4 kinds of stiffness. The results of the tests are summarized as follows: (1) judging from the load-settlement curves, higher stiffness of geotextiles is more effective for reinforcement, (2) horizontal deformation of embankments reinforced by geotextiles with lower stiffness is relatively large, and (3) earth pressure on the facing wall depends on the stiffness of geotextiles.
