Wave Propagation and Vibration Isolation in Soils
The goal of this study is to deal with the modelling and calculation of the ground-borne vibrations and the effect of the wave propagation on foundation response with emphasis on vibration screening systems. Herein, ANSYS FEM software program was used to simulate vibratory source induced wave propagation and dynamic foundation-soil interaction problem. Extensive parametric investigations on the screening performance of open and in-filled trench barriers have been done for both active and passive isolation cases. The obtained results are important for structural engineers since provide practical information and methods about the dissipation of the strong vibration energy.
