Diminishing Returns of Passive-Zone Improvement for a Braced Excavation in Coastal Soft Soil

Ground improvement can substantially reduce excavation-induced deformation in coastal soft soil, but increasing treatment depth does not necessarily produce a proportional mechanical benefit. This study investigates a 7.0 m-deep braced excavation using a two-dimensional Hardening Soil finite-element model established f...
