Discussion

Observational analysis compares slab-on-pile and embankment foundations in soft clay, indicating substantial differences in stability.

The slab-on-pile system minimized settlement to 0.519 m in one-dimensional analysis, while embankment settlements reached up to 2.533 m.
Finite element analysis showed slab-on-pile settlements of 0.775 m, significantly lower than the embankment's 1.038 m, highlighting their performance differences.
Using two analytical approaches, the study confirms that the slab-on-pile foundation has a shorter consolidation period and a higher safety factor.
Selecting appropriate foundation systems is crucial in coastal areas prone to land subsidence to improve infrastructure durability.

Setiawan et al. (2025) studied this question.
