Abstract

Piles are commonly adopted to overcome problems with soils that are highly compressible, have low shear strength and too weak to support the loads transmitted by the superstructure. However, since the beginning of geotechnical engineering profession, determination of pile bearing capacity has been a difficult task for engineers. In recent years, determination of bearing capacity of piles by static analysis and in-situ methods has been used by geotechnical engineers and has been subject to considerable number of researches. In this paper, different static analysis and Standard Penetration Test (SPT) based methods of estimating pile bearing capacity have been explained and compared. Pile dynamic test (PDA) results and in-situ testing results of Twin Lakes Resort Hotel Project at Laurel, Batangas were gathered. Estimated pile capacities from different methods were compared to measured pile capacity by log-normal and cumulative probability approaches. Comparisons showed that for SPT-based methods, Bazaraa & Kurkur method (1986) predicted the pile capacity with more accuracy and less scatter than the other methods. Whereas among the static analysis methods, the combined methods of Terzaghi (1976) and Meyerhof (1976) predicted pile capacity with more accuracy. Thus, this methods can be used alternatively for bearing capacity determination of piles in the similar site and soil conditions.
