Estimation of the Liquefaction's Risk of a Soil Deposit under Seismic Solicitations: Petrochemical Zone of Skikda City
This study consists in estimating the risk (potential) of liquefaction of a soil deposit saturated when it is submitted to a horizontal seismic excitement to its basis while using the approach in total constraints. This approach requires the determination of the shear constraint τa developed by the seismic solicitation, For the determination of τa, an equivalent linear dynamic analysis with concentrated mass has been used to adapt (iterable proceeding) the module of shear and the factor of damping according to the level of the resulting shear deformations because, the constraint-distortion diagram of the layer is nonlinear with dissipation of energy by hysteresis for each cycle. For this reason, in this survey, the behavior of soil has been represented by a hyperbolic relation of Hardin and Drenevich. For the determination of τl, the graph of Seed and al based on the results of the SPT. The report of the two constraints permits the definition of safety factor against the risk of liquefaction (CSL).
