520			_aThis thesis deals with (1) predictions of ultimate carrying capacity of piles, (2) consideration of the frictional and end bearing components of loads as computed by static data and when compared with the tension support experienced in the anchor piles of pile load tests, and (3) comparison of wave equation evaluations of pile load capacity with the ultimate loads determined from pile load tests. For this the procedure proposed by CHIN (1 972) was adopted. The results indicate that the effective stress approach to pile design gives much better agreement between prediction and actual recordings than the total stress method for shaft force component. The total stress method was found to overestimate the total force tor piles driven in soil with clay but to agree reasonably in the case of cohesion less soil. Reduction factor applied to walls driven piles in cohesion less soil are too conservative and the adhesion factors specified from TOMLINSON (1977) may have not been low enough for piles in cohesive soil from comparing wall force developed in pulling to total stress method. No good agreement was obtained using TTI programme's parameters except for piles driven through layered strata of soils with their tips found in sand.
