Centrifuge modeling of the behaviour of helical piles in cohesive soils from installation and axial loading

Soils and Foundations, 2022
Centrifuge modeling offers a viable tool for research in the soil-pile interaction, but this technique has not been used for helical piles in cohesive soils.

Theoretical and actual bearing capacity of driven piles using model piles in sand [PDF]

, 2014
In general, increasing of penetration rate may result in an increased of pile capacity. Occasionally, there were differences between theoretical and actual bearing capacity of the piles. Rate of penetration of pile influenced the pile bearing capacity.

Evaluation of actual creep length under heading up structures aprons

Ain Shams Engineering Journal, 2018
In this paper a 2D finite element model (SEEP 2D) is implemented to study the actual head loss along the sheet piles fixed at the ends of an apron of a heading up structure. Different scenarios for the thickness of the pervious layer under the apron, the
