The author has addressed the pile foundation engineering quandary of negative skin friction by reducing it with a bitumen coat applied to the pile surface. Unfortunately, the author's introductory example intended to portray the need for the bitumen coat is ...

This paper describes the finite element analysis and interpretation of a O-Cell static test in barrette founded on residual soil.

a few suggestions are made for unifying the terminology and style of geotechnical engineering papers and, notably, piling papers.

The advent of the wave equation analysis in the mid-seventies was a quantum leap in foundation engineering. For the first time, a design could consider the entire pile driving system, such as wave propagation characteristics, velocity dependent aspects (damping), ...

Design of piles requires understanding of how load is transferred from pile to soil and, less obvious but equally important, from soil to pile.

A unified design of piles and pile groups is proposed where in capacity, residual compression, negative skin friction and settlement are related.

This paper describes six methods to determine axial pile capacity directly from cone penetration tests data.

The old paper makes the mistake of separating the calculation of the settlement of the pile (pile group) from the transfer of the load applied to the pile head when determining the location of the neutral plane. The author's paper appears to have fallen into ...

This paper discusses the fallacy of the concept of the critical depth. The fallacy is due to neglecting residual loads in full-scale tests and stress-scale effects at model-scales, made measured load distribution appear linear below a certain "critical" depth. ...

Damaging compressive stresses can develop at the pile toe when piles are driven to bedrock or in bouldery conditions. High-strain testing methods using the Pile Driving Analyzer (PDA) have been used successfully to detect pile damage along the pile.
