ANALYSIS OF CAPPED PILE GROUPS SUBJECTED TO HORIZONTAL AND VERTICAL LOADS

This paper presents a method of analysis for an off-ground cap supported by piles embedded in a layered soil and subjected to horiztonal and vertical loads. The cap is modelled as a thin plate and the piles as elastic beams and the soil is treated as consisting of horizontal layers of different materials. Finite element theory is used to analyse the cap and piles while finite layer theory is employed to analyse the layered soil. Using program APPRAF (Analysis of Piles and Piled RAft Foundations) to carry out the analysis described above, comparisons of the behaviour of capped pile groups are made and factors affecting the displacements of capped pile group foundations are examined. Finally, an example related to three types of soils where the moduli increase with depth is illustrated. The results show that the present method is a powerful and useful way to evaluate the behaviour of capped pile foundations embedded in different types of soils and subjected to both vertical and horizontal loadings.
