Abstract

This paper presents an analysis of the chicken-foot foundation using the finite element method. The foundation is considered as a reinforced concrete slab resting on a number of reinforced concrete pipes filled with and surrounded by in-situ soil. The soil and the pipes were modelled by isoparametric solid elements while the slab was modelled by isoparametric thick-plate elements. The study was intended to illustrate the basic mechanism of the chicken-foot foundation. Three cases have been considered for the parametric studies. The parameters investigated are thickness of slab, length of pipes and spacing between pipes. It is shown that such a foundation improves the behaviour of the raft foundation. It is also found that all the parameters used in the parametric studies influence the behaviour of the chicken-foot foundation.

Abstract

This study presents the development of the finite difference method applied to consolidation analysis of embankments. To analyse the consolidation of the embankment as real as possible, the finite difference method in two dimensional directions was performed. Existing soils under embankments have varying stresses due to stress history and geological background. Therefore, Skempton’s parameter “A” which is a function of vertical stresses was taken into account in this study. Two case studies were chosen to verify the proposed method. It is found out that results obtained from the proposed method agree with either recorded data or results solved using another solution.
