Abstract

Before reaching the ground surface, the amplitude, duration and frequency content of the vertically propagating seismic waves can be modified by the local stratigraphy and soil physical properties. In this study, we evaluate the impacts of the soil shear wave velocity (Vs) and thickness (H) on the seismic ground response using 1D ground response analysis. Simplified soil profiles typical for the Saguenay Lac-Saint-Jean region (SLSJ) are considered defined with relatively thin glacial sediments overlaid by more than 100m thick marine sequence. Impedance contrasts exist at the bedrock interface and between the fine marine and glacial sediments. Time-domain nonlinear 1D numerical simulations are carried out with Deepsoil®. The seismic input at the bedrock level is defined with synthetic earthquake time histories compatible with eastern Canadian seismo-tectonic settings. It is found that the changes in the Fundamental period of the soil caused by changes in the thickness of the soil deposit and soil Vs have a significant impact on the surficial amplification.
