This thesis focuses on assessing the impact of different footing shapes on the undrained seismic bearing capacity of surficial foundations located near slopes. The study employs the PLAXIS 3D finite element software to conduct a comparative analysis, aiming to provide valuable insights for geotechnical engineers involved in foundation design in such scenarios. For this purpose, numerical models are created to simulate the behaviour of surficial foundations under seismic loading. Various footing shapes are examined during the analysis, considering the undrained soil properties, slope characteristics, distance between the slope and footing, and seismic loading parameters. The research findings highlight the substantial influence of footing shape on the undrained seismic bearing capacity of surficial foundations near slopes. As a result of the study, design charts specific to each footing shape are developed, offering engineers a tool to estimate the bearing capacity in similar scenarios. These design charts provide practical guidance for optimal foundation design and enhance the understanding of how footing shape impacts the seismic performance of surficial foundations near slopes.
