Abstract: This paper describes the development of a numerical model for simulating the shaking table tests on wrap-faced reinforced soil
retaining walls. Some of the physical model tests carried out on reinforced soil retaining walls subjected to dynamic excitation through
uniaxial shaking tests are briefly discussed. Models of retaining walls are constructed in a perspex box with geotextile reinforcement using
the wraparound technique with dry sand backfill and instrumented with displacement sensors, accelerometers, and soil pressure sensors.
Results showed that the displacements decrease with the increase in number of reinforcement layers, whereas acceleration amplifications
were not affected significantly. Numerical modeling of these shaking table tests is carried out using the Fast Lagrangian Analysis of Continua
program. The numerical model is validated by comparing the results with experiments on physical models. Responses of wrap-faced walls
with varying numbers of reinforcement layers are compared. Sensitivity analysis performed on the numerical models showed that the friction
and dilation angle of backfill material and stiffness properties of the geotextile-soil interface are the most affecting parameters for the model
response
