Comparative Analysis of Deep Foundation Performance Under Different Seismic Loading Conditions

This research paper investigates the critical relationship between soil properties and foundation performance during seismic events. Through comprehensive analysis of case studies and experimental data, this study demonstrates that soil characteristics—including density, moisture content, particle size distribution, and stratification—significantly impact how foundations respond to earthquake loads. The research confirms that site-specific soil characterization is essential for resilient foundation design in seismic regions. Several key factors are identified as most influential: soil liquefaction potential, dynamic soil stiffness, and soil-structure interaction effects. Based on these findings, the paper proposes design recommendations for improving foundation resilience in various soil conditions and emphasizes the importance of integrated geotechnical and structural approaches for earthquake-resistant construction.
