Prediction of the Axial Bearing Capacity of Piles by SPT-based and Numerical Design Methods The prediction of the axial capacity of piles has been a challenge since the beginning of the geotechnical engineering profession. In recent years determining bearing capacity of piles from in-situ testing da...
N = N value derived from Standard Penetration Test (SPT) D = depth of footing (m) (ft), and B = width of footing (m) (ft). Note: All Meyerhof equations are for foundations bearing on clean sands. The first equation is for ultimate bearing capacity, while the second two are factored...
Employing different design methods, resulting in a wide range of bearing capacity estimations, complicates the selection of an appropriate design scheme and confirms the existence of model error along with the inherent soil variability in bearing capacity prediction. This paper tends to evaluate ...

One of my ancient texts, Peck Hansen and Thorburn, "Foundation Engineering", shows tables from which you can get bearing capacity factors Nq and Ngamma for SAND, based on N values. For clays, PH&T say "the standard penetration test is not so reliable an indicator of the...
The present investigation employs relevance vector machine (RVM) and long short-term memory (LSTM) models to predict the time-dependent bearing capacity of concrete piles. Each RVM model (SRVM) is configured by each linear, polynomial, gaussian, sigmoid,

analysis of PDA were consistently higher than results from the MLT. A coefficient of 0.9 or a 10% reduction is suggested to be applied to values derived from PDA. It is also observed that the longer the time interval, the greater the shaft friction contribution is towards the pile capacity....
Based on the empirical models, the ultimate capacity of the piled foundation can be estimated. However, the suggested values were based on test data obtained from different geographical locations and the pile may not be constructed using a similar construction methodology. Furthermore, no clear corre...
