Abstract: Field pour concrete cased pile with vibrated and steel tube mould technology is a new ground improvement technology developed independently by Hohai University. This new pile style is suitable for soft areas. Load transfer is studied by means of an axisymmetric finite element elastoplastic model that includes interface elements for representing slippage , pile-soil separation and soil nonlinear behavior. Numerical results indicate that good agreement exists between the finite element prediction and the field test for the head load-settlement curve. Inner frictional resistance, outer shear stress, end bearing and effects of soil plug those can not be investigated by field test are also studied.

Key words: field pour concrete cased pile, soil plug, load transfer, finite element method
