Abstract

Wave barriers are intended to mitigate the transmission of vibrations in the soil. In this study, two-dimensional finite difference element analysis has been carried out, to investigate the efficiency of open and in-filled barriers under dynamic loading without or with presence of the structure. In this contribution, on the basis of the general basis for yield, failure and potential functions in plasticity in soil, two constitutive models to studying the rate of soil response in the elastic and elastoplastic range have been investigated. From numerical analysis be concluded that the results achieved with assigning elastic properties to the soil material doesn’t follow the trend with the result that have been achieved from analysis of the model with non-linear properties of soils, with higher values at all points. Presence of structure has a significantly larger effect on efficiency of barriers on reducing surface wave energy with assigning nonlinear modulus to soil.
