Evaluation of soil liquefaction and earthquake-induced deformations based on ground motion parameters
Abstract
This review investigates the relationship between soil liquefaction and earthquake-induced deformation mechanisms through a structured synthesis of the available literature, representative earthquake case histories, and field observations. By integrating findings from literature, field observations, and numerical studies, it is demonstrated that peak ground acceleration (PGA), which forms the basis of conventional approaches, is not sufficient when considered alone. The study emphasizes that the liquefaction process consists of two fundamental stages: liquefaction triggering and post-liquefaction permanent deformations. The findings indicate that liquefaction triggering is largely associated with PGA, whereas deformations such as lateral spreading, settlement, and permanent ground displacements show a stronger correlation with peak ground velocity (PGV) and peak ground displacement (PGD). Recent earthquake data further reveal that different deformation patterns may occur in regions subjected to similar PGA levels, highlighting the significant influence of frequency content, duration, and energy components of ground motion on soil behavior. In conclusion, soil liquefaction is not merely a triggering phenomenon but a complex engineering problem involving multidimensional deformation processes. Therefore, it is essential to adopt multi-parameter and performance-based analysis approaches that incorporate PGA, PGV, and PGD together for reliable engineering assessments.
