Using discrete-element method hindcasting of screw pile performance for practical design

Screw piles have been used to support a variety of structures due their ease installation and high axial capacity. Recently, screw proposed as an alternative foundation solution for offshore renewable quiet or silent installation. Due variable geometry, design prediction requirements its effect on in-service capacity may be challenging. In this research study, the discrete-element method (DEM) is numerically recreate series onshore field tests. The aim study investigate ability DEM practical tool deployment piles. case geometric helix pitch torque tensile installed into sand investigated. results show that pile appears little torque. has potential procedure complex where simulation needs capture effects.
