| Summary: | The use of timber or concrete piles offers one solution to the problem of stability and settlement posed by construction of road or highway embankments
on soft ground. The idea is to transfer most of the applied load on to a grid of piles, and for reasons of economy, the piles should be spaced as widely as possible and capped individually rather than by a continuous slab. However
the mechanism of load transfer from ground to the top of the pile cap appears not to be fully understood. Design methods are empirical, based on the results
of low stress level model tests on sand, and on field experiences. Using centrifugal and laboratory model tests the influences of parameters such as fill
height, pile area ratios and fill properties on the load sharing between the pile and ground are examined and described in the paper. |
