Modeling And Analysis Of Concrete Filling Pile Under Static And Danamic Loads By ANSYS

As the interface between pile and geotechnical media effects the mechanical behaviors of the pile foundation significantly, a reasonable model is critical in the calculation and analysis of pile, based on the theory analysis of the pile by other scholar, the finite element analysis method can be used on piles through the combination of vertical and horizontal dynamic loads, and on the engineering practice.When we analyze the pile and soil by the usage of the finite element analysis method, Goodman element often be used to simulate the interface. By introducing non-linear behaviors (concrete behaviors, soil elastic and plastic behaviors and several classical methods of interface element) ,and recur to ANSYS finite element currency software and based on APDL language programme form, the author made great effort on the mechanics characteristic modeling of pile foundation by the vertical and horizontal dynamic loads.Between the analysis, according to interface problem, we adopt increment Lagrange and dynamic finite element method, and build finite element calculate formula and model of axial symmetry isoparametric element, and introduce in detail simulation analysis of elastic interface theory and finite element model.
