RESEARCH ON PILED FOUNDATIONS - HISTORICAL REVIEW AND FUTURE NEEDS

The report, based on a lecture by R W Cooke to the British Geotechnical Society in February 1985, summarises advances made in the last 50 years showing how the accepted design practice has improved with an understanding of the principles involved. The emphasis is placed on the work of the Building Research Establishment (BRE). Although early work on the driving stresses on driven piles is still relevant, recent research has shown the importance of field investigations in obtaining soil parameters for design. Different safety factors are used for the base and shaft capacities of bored piles. The understanding of pile groups behaviour has been improved by the use of computer based analysis techniques such as finite elements. It has been shown that, in the case of piled rafts, the raft carries a larger proportion of the load than was at first imagined. Methods of effective stress analysis are discussed; some recent results showed that London clay pore pressures due to the shaft dissipate within a few days, but slight increases in pile capacity were recorded over many months.
