Evaluation of static and dynamic methods for determining the bearing capacity of the driven pipe piles

摘要

Different static and dynamic methods exist for determining the pile bearing capacity which theprecision of the results of each method depend on the condition of the soil and type of pile as well asaccessibility to necessary information. In this study bearing capacity of driven pipe piles in cohesion soil andthe driving progress in a practical project are evaluated. For this purpose the information of 208 driven piles infour A, B, C and D regions in total areas of 1500 m2 were used. Using this information, dynamic relations ofpile bearing capacity in fine grained soil was compared with the result of the static relations. This study hasbeen shown that ENR dynamic relations, modified ENR and new modified ENR have good correlation withstatic methods.
