[Truncated] This research has investigated the performance of piles in non-homogeneous elastic plastic media subject to vertical or torsional loading, the time-dependent response of a vertically loaded pile due to either creep or reconsolidation subsequent to pile driving, and the behaviour of vertically loaded pile groups. Closed form solutions have been established accordingly, and numerical programs, GASPILE and GASGROUP have been developed. The closed form solutions were firstly developed for vertically loaded single piles. Secondly, in a similar manner, solutions for single piles subject to torsion were generated, in light of a newly established torsional load transfer model. The effect of non-linear soil stress-strain properties modelled using a hyperbolic stress-strain law, has been investigated through the program, GASPILE, for both vertical and torsional loading. Thereafter, the solutions for vertically loaded piles were extended to account for visco-elastic response, with a newly established visco-elastic model.
