This research paper investigates the influence of vertical variability of the shear modulus on the seismic responses of slopes. Soil state variables in space and time are due to complex geological conditions. As a result, soil properties vary from one point to another. For this reason, due to the uncertainty associated with its inherent spatial variability, and limited available information, soil properties can be considered as random variables. The random soil property of interest (elastic modulus) is modeled as a random field by adopting the lognormal distribution, which enables analyzing its large variability. However, the proposed methodology involves the generation of a random field for shear modulus, achieved through rigorous Monte Carlo simulations. Notably, the random variables used in these simulations are precisely characterized by their first and second moments, which are respectively the mean and variance, thoughtfully estimated from in situ samples. The results showed that the acceleration response spectrum obtained with a CVG value of 0.25 and 0.5 is greater than the acceleration response spectrum obtained with the deterministic analysis. This research aims to provide a comprehensive understanding of the uncertainties associated with soil properties, particularly shear modulus, and its implications for the seismic stability of slopes.
