INTELLIGENT INCIDENT TRIAGE IN HIGH-VOLUME PAYMENT PROCESSING SYSTEMS VIA HIERARCHICAL GRAPH DIFFUSION NETWORKS

The consolidation behavior of soft soil foundations subjected to cyclic loading presents a complex multiphysics problem critical to the stability of transportation infrastructure and offshore structures. Traditional continuum mechanics approaches often struggle to capture the granular rearrangements and micro-structural evolution inherent in soft clays and silts under repeated stress applications. This study employs the Discrete Element Method (DEM) coupled with a coarse-grid fluid dynamics scheme to simulate the hydro-mechanical response of soft soil assemblies. By modeling the soil skeleton as a collection of bonded particles and the pore fluid as a continuum interacting through drag forces, we investigate the generation and dissipation of excess pore water pressure and the resulting cumulative settlement. The simulation results reveal that cyclic loading frequency and amplitude significantly influence the breakdown of inter-particle bonds and the reorganization of the force chain network, leading to non-linear consolidation rates that deviate from classical Terzaghi theory. The study further elucidates the mechanism of strain accumulation, showing that particle reorientation acts as the primary driver for permanent deformation after the initial breakdown of soil structure. These findings provide micro-scale insights that enhance the predictive capability for long-term foundation settlement.
