A discussion of a paper with the aforementioned title by Murff and Hamilton, published in this journal (Volume 119, Number 1, January 1993), is presented The discussion focuses on laterally loaded piles in layered soils Maugeri, Castelli, and Motta assert that the authors' method overpredicts the ultimate lateral resistance on the pile Discussion is followed by closure from the authors

P-ultimate for undrained analysis of laterally loaded piles. discussion and closure

Previous studies on laterally loaded piles in clay have mainly focused on flexible and rigid piles. Little attention has been paid to semi-rigid piles (whose pile–soil stiffness lies somewhere betw...

Cyclic lateral response and failure mechanisms of semi-rigid pile in soft clay: centrifuge tests and numerical modelling

The results of theoretical and experimental studies of the properties of clay soils lead to a very simple equation for computing the ultimate bearing capacity or maximum pressure to which the soil can be subjected without complete failure. This equation refers to a rectangular footing having a width B and length L. The expression is Q(sub d) equals 2.85 Q(sub u) (1 plus 0.3 B/L) in which Q(sub u) is the unconfined compressive strength of the clay beneath the loaded area, and Q(sub d) is the ultimate bearing capacity. The unconfined compressive strength of a clay soil can be determined readily by relatively rapid and inexpensive methods.
