Dynamic Testing of Homogeneous Embankment Models
Physical model tests were performed on homogeneous cohesionless embankments subjected to idealized ground motion. During the testing, the response of model embankments to a sinusoidal input motion was monitored, and acceleration and displacement data were collected. An analytical model, based on Newmark's sliding block theory, was used to estimate the permanent displacement of sliding blocks subjected to input dynamic motion. Analytical results were compared with physical model test results to assess the validity of the mathematical model. It was concluded that the mathematical model did not accurately predict the deformation of homogeneous cohesionless embankment models because of difficulty in determining the effective shear strength of the material at low normal stresses.
