|Abstract:||An analytical procedure is developed to study the liquefaction potential and seismic response of saturated sands. Method treats the saturated granular soil system as a two-phase nonlinear medium with constituent materials being the granular solid skeleton and the pore water. An elasto-plastic stress-strain rule is developed to simulate the behavior of soils under cyclic stresses. A two part stress path model is used to define the relationship between effective stresses and the cyclic shear stresses. The first part of the model simulates the behavior of saturated sands prior to initial liquefaction and the second part of the model covers the post-initial liquefaction behavior.
The model developed is used to simulate large scale undrained shaking table tests on saturated sands. Reasonable agreement is observed between the experimental and analytical results. Finally, a parametric analysis is made to investigate the effects of the base motion characteristics and properties of the layers.
