A case study of soil-pile interaction in soft soils

Publikation: KonferencebidragPaperForskningpeer review



The results of soil-structure interaction of driven steel piles installed through soft soils are pre-sented. Two instrumented, 12 m embedment, 406 mm diameter steel piles were installed at a construction site in Esbjerg, Denmark. One of the test piles was bitumen coated. The test piles were driven through 3.5 m of re-claimed sand and 3.6 m of soft soil into underlying sand layer. To investigate the soil-pile interaction due to pile installation and surcharge loading adjacent to the piles after installation, the test piles were instrumented with distributed fibre optic strain sensors along the full length of the piles. It was found that the test piles experienced compression loads after installation and lateral deflections due to surcharge loading in the soft soils. This case study documents the existence and magnitude of residual loads in driven steel piles after installation, the influence of bitumen coating and the effect of lateral thrust on the piles in an upper soft soil layer.
