Development of a damage simulator for assessing the vulnerability of electrical equipment to seismic risk in the Saguenay-Lac-Saint-Jean region

The main objective of this research project is to determine the seismic risk for Hydro-Québec equipment and facilities in the Saguenay-Lac-Saint-Jean region. First, the project aims to develop a 3D model of the regional subsurface. We then use shear wave velocity (V_s) within the surficial deposits to evaluate the amplification effects of seismic shocks. These effects will be estimated through geophysical and geotechnical tests conducted as part of the project and the use of existing data available for the region. We will zone soil classes by applying a 3D model of the ground and measuring the speed of the shear waves within the first 30 m of soft deposits. This geological and geotechnical model will evaluate the seismic hazard. Our second major objective is to compile information related to the vulnerability of Hydro-Québec equipment to seismic events. Finally, we will develop a tool to determine the risks to this equipment within selected seismic scenarios.
