Settlement-reducing piles are often a very economic and attractive foundation solution. The concept is used increasingly for different types of foundation problems.
However, it is not possible to respond to your question as it is too general. However, proceedings from many conferences have addressed this aspect of foundation support.
A state-of-the-art on the combined use of piles and rafts is presented in the paper "Practical design procedures for piled raft foundations" by H. G. Poulos, Chapter 16 of the book "Design applications of raft foundations", published by Thomas Telford (UK), 2000, Editor J. A. Hemsley, pages 425-467. You may also refer to a similar shorter paper by Poulos, "Piled raft foundations: design and applications", Geotechnique, 2001, Vol. 51, No. 2, March, pages 95-113. These papers include an overview of available methods for the design of piled rafts.
I am a geotech.consultant doing my Ph.D IN THIS field.I have designed a G+10 floor building with piled raft and monitering the settelement for my doct.work.I have started the analysis in ansys.can you be more specific in your need With respects V.Balakumar
It is not too difficult to design a piled raft structure if you have a good ideal on how the loading distribution is and some analysis tools for pile group effect with consideration of structural interaction between the pile-to-raft, pile-to-soil and raft-to-soil.
I've just submitted a paper (Liew, S. S., Gue, S. S. & Tan, Y. C. (2002), "Design and Instrumentation Results of A Reinforcement Concrete Piled Raft Supporting 2500 Ton Oil Storage Tank on Very Soft Alluvium Deposits", Ninth International Conference on Piling and Deep Foundations, Nice, 3rd - 5th June, 2002).

Dear Prof. My name is Maryam Akbarzad . I am living in East Azerbayjan of Iran. I am doing an MS in Geotechnical Engineering at the University of Tabriz. My subject of thesis is Investigaion about equations and the methods of estimation of the coefficient of subgrade reaction and analysis of the sensitivity of it in design of foundations and retaining walls. that would be very kind of you to provide me with any more lectures, books and etc. best regards Akbarzad
