New Method for Predicting the Ultimate Bearing Capacity of Driven Piles by using Flap Number
Fatehnia Milad,Tawfiq Kamal,Hataf Nader,Ozguven Eren Erman 대한토목학회 2015 KSCE JOURNAL OF CIVIL ENGINEERING Vol.19 No.3
A new method was proposed to predict the compressive bearing capacity of driven piles based on the number of hammer strikes inthe last one meter of pile penetration (known here as Flap number). To collect the data, a literature review was done on technicalpublications and pile driving record reports that were accessible to the authors at the time of publication. The data of a hundred drivenpiles including Flap number, basic properties of the surrounding soil, pile geometry, and pile-soil friction angle was collected. Thesedata were initially used in the artificial neural network to establish a relation for predicting pile capacity. Subsequently, by usinggenetic programing and linear regression, equations for determining pile bearing capacity with respect to the Flap number, soilparameters, and pile geometries were proposed. Finally, the performance of all applied methods in predicting the pile bearingcapacity were compared. The utmost importance was given to the comparison of the accuracy of the three models as well as the errorestimation.
