Abstract | The spatial variability of marine soils has received increasing attention from geotechnical engineers, particularly for quantifying the probability of specific performance outcomes. However, the bearing capacity of a typical marine stratum comprising a sand layer overlying spatially random clay remains underexplored in current literature. To address this gap, the present study employs Monte Carlo simulations (MCSs) in conjunction with advanced computational techniques to evaluate the bearing capacity of such layered soils. Utilizing upper-bound limit analysis and a range of practical statistical parameters, the study presents numerical results in the form of probabilistic design charts. These charts provide valuable tools for estimating the probability of failure (PF) associated with different safety factors. By enhancing the understanding of geotechnical reliability and safety, the proposed charts support more informed and rational design decisions. This approach not only bridges the gap between traditional deterministic methods and modern probabilistic assessments but also more accurately reflects actual marine soil conditions. © 2025 The Authors |
