FEM modelling of screw displacement pile interaction with subsoil [PDF]
Archives of Civil Engineering, 2023 Predicting the Q–s settlement characteristics of piles is an important element in the designing of pile foundations. The most reliable method in evaluating pile-soil interaction is the static load test, preferably performed with instrumentation for ...

Results of the “DPDT-Auger” Research Project on Screw Displacement Piles
Architecture, Civil Engineering, Environment, 2023 The main objective of the “DPDT-Auger” research project was to test the prototype DPDT auger for forming screw displacement piles in the ground (patented in Poland in 2020). An additional aim was to develop design methods and rules for the making of such

The Analysis of Soil Resistance During Screw Displacement Pile Installation [PDF]
Studia Geotechnica et Mechanica, 2015 The application of screw displacement piles (SDP) is still increasing due to their high efficiency and many advantages. However, one technological problem is a serious disadvantage of those piles. It relates to the generation of very high soil resistance

Identification of residual force in static load tests on instrumented screw displacement piles
Studia Geotechnica et Mechanica, 2021 Occurrence of the so-called residual force of an unknown value significantly disturbs interpretation of static load tests performed on piles equipped with additional measuring instruments.

The Baltic Journal of Road and Bridge Engineering, 2023 The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There is also insufficient research on piles in silty soils. Therefore, five cone penetration tests (CPT) and one piezocone penetration test (CPTu) using direct methods ...

Indian Geotechnical JournalAbstract The determination of pile bearing capacity using the load–settlement relationship has been widely recognised as an effective means of directly determining the bearing capacity of a pile through in situ tests. Among the various techniques available for such investigations, the seismic cone penetration test (SCPTu) stands out as one of

Proposal for calculating the bearing capacity of screw displacement piles in non-cohesive soils based on CPT results [PDF]
Studia Geotechnica et Mechanica, 2012 Abstract Screw displacement pile technology is relatively new and is still being developed. A specific characteristic of those piles is their very considerable influence on soil properties during the installation, which renders classical bearing capacity calculation methods insufficient.
