NUMERICAL AND PARAMETRIC ANALYSIS OF EXCESS PORE PRESSURE BEHAVIORS IN UNREINFORCED EMBANKMENTS ON SOFT SOILS

Resumo

This study, the third in a series of three, examines the behavior of excess pore pressure in four unreinforced embankments on soft soils. To this end, numerical modeling using Abaqus software is employed. The embankments, comprising granular materials, have dimensions of 3.5 meters in height and 17 meters in width. The underlying soft soil layer extends horizontally for 30 meters, with thicknesses varying from 5 to 20 meters. The investigation assesses the influence of overconsolidation ratio, recompression index, and critical state slope on excess water pressure behaviors through four different normalization methods. The results indicate that variations in recompression index exert a more significant impact on excess pore pressure behaviors compared to those of overconsolidation ratio and critical state slope. The implications of these findings on slope performance and stability are discussed. Additionally, the study underscores the efficacy of Abaqus software in modeling geotechnical problems.
