Screw Pile, Horizontal Bearing Capacity, Finite Element, Parameter AnalysisAbstract
This paper studies the horizontal bearing capacity of screw pile under the limit state of normal use in silty sand soil, simulates the horizontal loading process of screw pile by ABAQUS software, introduces the creation process of the model of screw pile, material attribute selection and finite element mesh division, etc. The influencing factors and variation rules of horizontal bearing capacity, plastic zone of soil mass, failure mode of soil mass and pile deformation mode of screw pile are studied, and a more comprehensive parameter basis is provided for the establishment of prediction formula of horizontal bearing capacity of screw pile. The parameters of screw pile diameter, screw blade diameter and screw blade buried depth are analyzed. It provides some support for the theoretical analysis and engineering practice application of screw pile.
