Basically it is assumed that seismic waves while passing through different layers of earth are
reflected, refract, refraction and absorption and distribute and reduce energy. In this study, porosity and
elastic properties of objects are used in the design of the proposed model to develop further wave refraction
and absorption. In this method the longitudinal wave energy is relatively absorbed by a layer of artificial
soil and has been amortized, so that seismic wave’s energy is wasted for the displacement of layers and the
desired structure remains with relative low movement. According to the results of laboratory model, elastic
refractory materials (dense PVC) were used because the merge rate of elastic materials is more than other
materials. In the damping phenomenon, the object's internal kinetic and strain energy rate quickly decrease.
Therefore, for wave distribution and absorption in the earth, geomembranes were designed in very thin
layers and were used in soil layers. Finally, the model defines the geomembrane related parameters and
offers a schematics diagram of the plan.
