Itasca - Ground-Structure Interaction Consulting Services

Ground-structure-interaction is the iterative effect that ground deformations have on any emplaced stabilizing structures (beams, sheet pile walls, piles, liners, anchors, etc.), and vice versa. This is particularly important for heavy structures resting on relatively soft soils (Wolf, 1985). While limit equilibrium (LE) doesn’t capture ground-structure-interaction fully, Itasca’s ...
