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 ...

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

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 ...

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

Experimental study on bearing mechanism of screw cast-in-place piles under vertical loads
Yantu gongcheng xuebao, 2021 The screw cast-in-place pile is a kind of variable-section cast-in-place pile with cylindrical top and threaded bottom. Due to its special construction technology and section form, the bearing mechanism of screw piles is different from that of piles with
