LABORATORY MODEL STUDY ON GEOSYNTHETIC REINFORCED SOIL RETAINING WALLS

A study is reported which investigated the failure mechanisms of both extensible and inextensible reinforced soil model walls, and compared their performance. The study verified available design approaches, and assessed the methodology used to obtain relevant material properties and interaction parameters. The geosynthetic reinforcing materials used in the tests were as follows: woven polyester geotextile strips; nonwoven geotextile strips; and plastic grids. The main experimental results on model walls with the geosynthetics are presented together with practical conclusions drawn from them. The laboratory models illustrate that ther are three failure mechanisms of the reinforced soil structures: breakage of reinforcements, sliding the reinforcements, and excessive facing displacements in the case of extensible reinforcements. Instrumentation provided measurements of displacements along the reinforcements. The importance of confined material properties of reinforcements is demonstrated.
