Evaluation of Static and Dynamic Methods for Determining the Bearing Capacity of the Driven Pipe Piles

Determination of pile capacity is always a major concern for safe geotechnical engineering design.Different direct and indirect methods are proposed for pile bearing capacity determination such asstatic and dynamic approaches. Each method depends on soil conditions, pile type as well asaccessibility to necessary information. In this study, bearing capacity of driven pipe piles in cohesive soils are investigated. For this purpose, the information of 208 driven piles in four sites in total areas of 1500 m2 are obtained. Using this information, dynamic relations of pile bearing capacity in fine grainedsoil is computed and compared with result of static relations. Results indicate the accuracy of the Engineering News Record (ENR), modified ENR and new modified ENR approaches in comparison with static methods
