Deterministic and Probabilistic Analyses of the Bearing Capacity of Screw Cast in Situ Displacement Piles in Silty Soils as Measured by CPT and SDT

The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There also insufficient research on silty soils. Therefore, five cone penetration tests (CPT) and one piezocone test (CPTu) using direct methods were utilised to determine the load-bearing four Estonia. In addition CPT sounding data, static-dynamic (SDT) results used analyse load-beating piles. Both deterministic probabilistic analysis. Characteristic values as a 95% reliable mean 5% fractile for parameters, according Eurocode 7, included. Additionally, Monte Carlo simulation was included reliability-based design (RBD). capacities soils, here based SDT similar. adaptation pile analysis certainly deserves attention further investigation. For both types, 7 method provided best all pile-bearing absolute difference varied within ±11% between average, RBD characteristic values.
