Abstract

Placement of approach fill material on soft ground can result in time-dependent movements within the clay and significant passive loading on pile groups. This is attributed to passive pile loading which is occurred as a result of relative pile-soil displacement. Since the 1990s, marine reclamation has actively progressed in South Korea, connecting with new land development such as New Songdo city, Incheon Newport, and Busan Newport, representatively. Special focus has been given to lateral soil-structure interaction problems related to passively-loaded pile groups. Based on a large deformation finite element (LDFE) analysis, this paper presents the results of numerical investigation into time-related passive loading on pile groups adjacent to embankment on soft ground. It is identified from parametric study that passive pile loading is primarily governed by soil profile, pile head boundary condition, magnitude of embankment load, and average degree of consolidation. Also, the results allowed quantification of differences in the magnitude of passive loading on the piles between undrained and drained phases.
