Continuous Flight Auger Analysis Using Finite Element Method
Abstract
The paper presents the finite element model of a single continuous flight auger (CFA) piles used in clay soils, including the properties of the soil contact area. Also, the mesh type used finite element mesh is described. The design calculations are presented for single CFA piles under the static compressive loads. Recommendations are given on the parameter assignment for soil/pile interaction and the type of the finite element mesh used in the analysis of the setting and bearing capacity of single CFA piles. A comparative estimation is given for the numerical calculation results and field tests.
