“…Several 3D finite element method (FEM) programs have been developed since the 1990s [1,2], and with the recent improvements in computer software and hardware technology, performing large and complex geotechnical 3D finite element analysis is no longer challenging and expensive. Moreover, many constitutive models have been developed in the last 50 years, contributing to the development of geotechnical analysis using FEM [3][4][5][6][7][8][9][10][11][12]. Each model can express ground behaviors, such as anisotropy, dilatancy characteristics, over-and secondary consolidation, and creep.…”

Although geotechnical problems are inherently three-dimensional (3D), they are frequently approximated by one-dimensional (1D) or two-dimensional (2D) analyses. These simplifications are often based on certain assumptions. However, the use of simplified analyses under conditions where the 3D effects cannot be ignored reduces the accuracy of future predictions. This study aimed to investigate the relevance of plane strain analyses and 3D analyses, considering the 3D effects on typical load problems. In this study, 3D parametric analyses were conducted using several models with different embankment lengths in the longitudinal direction. The elastoplastic constitutive model (The Sekiguchi-Ohta model) and the linear elastic model were used to investigate the influence of the embankment shape and soil material on the 3D effects. This study confirms that the 3D effect factors help estimate the displacement of each part while considering the 3D effects from the analysis results obtained by applying the plane strain condition.
