ABSTRACT

This research investigates the dynamic stability of rubble mound breakwater under varying foundation soil conditions, including rocks, vibro-compacted fill, sand reinforced with stone columns, and sand. The study also explores different mesh sizes (medium, fine, and very fine) using the Plaxis 2D software based on the finite element method. The study aims to assess the response of the models of the rubble mound breakwater under different combinations of frequency and amplitude of dynamic loading. A comprehensive parametric analysis is conducted to explore the impact of these factors on breakwater stability. The findings reveal that the choice of foundation soil has a significant influence on the response of the rubble mound breakwaters during dynamic loading. Rigid soil provides higher stability, while reinforced sand columns and vibro-compacted fill enhance load-bearing capacity. Additionally, the mesh size employed in the numerical simulations affects the accuracy of the results, with finer mesh sizes offering more precise predictions of breakwater behavior. The study provides valuable insights into the assessment of rubble mound breakwaters for seismic conditions. This research contributes to the field of geotechnical engineering by improving our understanding of the interplay between foundation soil characteristics, mesh size, and dynamic loading effects on rubble mound breakwater stability. The outcomes will aid in the development of more resilient coastal and seismic protection structures, ultimately enhancing disaster mitigation and infrastructure resilience.
