STRESSES AND DEFORMATIONS IN GEOTEXTILE REINFORCED MODEL WALLS

This paper presents a study of geotextile reinforced model walls subje cted to vertical surcharge. Different reinforcement layouts were teste d. Vertical stress distributions were measured at the base of the wall s as well as internal displacements and horizontal displacements at th e face of the wall. Comparisons between predictions and measurements w ere also made. The results showed that the reinforcement arrangement u sed in the wall can significantly affected its face displacements and the stresses at its base. Theoretical predictions of stresses and disp lacements in geosynthetic reinforced walls are sensitive to some soil or reinforcement parameters usually unavailable in routine works.
