7 Jan 2004: However, the introduction of pore pres-sures as extra unknown primary variables during the "nite element analysis necessitates some extraparameters. ... Although the shape of these graphs might raise some concern, the actual scaleof error is very small

2 Feb 2004: A plastic hinge was assumed to form in the pile at some depth. ... The results indicate that there was considerable densification at site B, and some densification at site C.

6 Jan 2004: 15(b) is as expected, the undrained path leading to some- what larger strains as it traverses through states of high stress ratio at a reduced mean effective stress. ... In some cases, this assumption could usefully be made without introducing any
