Review of behaviour of piled raft foundations (R83)

Review of behaviour of piled raft foundations (R83)


Available only as a PDF

Structures have been constructed above piled raft foundations for many years, yet little guidance exists for the engineer on methods of analysis and design. Particular problems are maximum and differential settlements of the raft, apportionment of applied structural load between the piles and the base of the raft, and the distribution of these pile loads and raft base loads across the foundation. Many of these problems are also directly related to pile groups, where the structural connections to the piles are made above ground.

This report deals mainly with the behaviour of such pile groups subjected to vertical applied loading, with particular reference to piled raft foundations in cohesive soils. A brief account is given of various methods of pile group analysis available, and their application to design practice is discussed.
