What is the most effective method to predict the settlement of a group of floating piles?
no substratum is near and the piles are supposed to work only in the shaft friction.
Dear Friend,
I think that the attached articles are colsely related to your subject, I hope you get to find the answer.

Dear Professor Mohammed,
The attached research articles are so helpful.
Thank you Sir.
settlement of floating pile can predicted by shcerteman methode. you can read literature by philip p coduto or you can make a model by plaxis
Dear Tabchouche,
The settlement of floating piles embedded in sandy soil can be estimated by using either Skempton's method or Meyerhof's method. Also, in case of a floating piles embedded in clay soil, the settlement of piles can be estimated using equivalent raft approach. The details about these methods can be referred from the text books named 'Pile design and construction practice' authored by Michael Tomlinson and John Woodward or text book named 'Pile foundation analysis and design' authored by Poulos H.G and Davis E.H. ok all the best..
Dear @Karthigeyan,
Thank you for you answer or for the suggestion of all those valuable boobs and publications. I'm realy wondering about the method of estimation of the floating piles settlement installed in an heterogeneous soil.
Best regards.
Dr. TABCHOUCHE Seifeddine.
If you look for a simple calculation and fast solution to do problem of pile group settlement it is very easy to use the equivalent pile foundation method where the pile group is either substituted with the equivalent caisson or slab foundation.
Dear Mr. Josif Josifovski,
Thanks for your answer,
Actually, I'm looking for the most effective methods to estimate the bearing capacity and to predict the settlement of a group of floating piles installed in heterogeneous soils, I didn’t find any analytical publication treated this problem.
Regards,
Dr. Tabchouche seifeddine.
Dear Tabchouche,
The bearing capacity of a floating pile group installed in heterogeneous soil conditions can be calculated by the summation of the skin friction mobilized in individual layer for the single pile. The group pile capacity is by assuming the group efficiency as 1, so, the capacity of a pile group is number of piles multiplied by single pile capacity. The most reliable method for pile group settlement is calculated by using pile load test results. The pile group embedded in layered clay soil is calculated based on consolidation test results using equivalent raft method. The methods mentioned above is an effective method for calculating bearing capacity and settlement of the pile. You could find out these details on capacity and settlement of the pile group in standard pile related text books as listed in my previous message..ok all the best..
Dear Tabchouche,
Professor Harry Poulos, Emeritus Professor from the University of Sydney and a Senior Principal Consultant with Coffey & Partners, has graciously (and generously) agreed to allow post a PDF version of the seminal book Elastic Solutions for Soil and Rock Mechanics (co-authored with the late E.H. Davis). Professor Paul Mayne and Carol Maddox of the Georgia Tech Geosystems Group are also to be thanked for their efforts in producing these PDF documents. You can check in this link: http://research.engr.oregonstate.edu/usucger/PandD/PandD.htm
Dear Karthigeyan . S
Thank you for the detailed answer, I see that the pile load test is the most relevant method to bearing capacity analysis especially in case of very heterogeneous soils.
