questo è il modello dell'opera

In order to assess the effects (3) and (4), it has been used a synthetic response parameter defined as the ratio between the maximum acceleration at the 2D model surface, amax,S, and the peak acceleration at the surface evaluated in free field conditions, amax,FF (Fig. 3c,d and e). The model geometry produces, overall, seismic motion amplification behind the walls and at the excavation center, due to focusing phenomena of the waves, and seismic motion attenuation in front of the wall related to diffraction phenomena of seismic waves.
