Stress Analysis of Screw-Bored Compaction Cast-in-Place Piles

Abstract

Based on the current research status of screw-bored compaction cast-in-place piles (screw piles for short) and using ANSYS finite element software, in this research, a simulation analysis of the pile axial force and the side friction was conducted for three types of screw piles with different screw length ratios under vertical loading. The modeling analysis results were compared with the engineering data from a practical project in Anyang City, Henan Province, and the finite element model was validated. This research determined the effects of the screw length ratios on the pile axial force and the side friction and provided a theoretical foundation for the engineering design of a screw pile.
