Hyperbola method can be used to predict the ultimate bearing capacity of pile

of which P-s curve is an adjustment curve. The ultimate bearing capacity of squeezed branch pile is predicted based on seven piles from two different sites by hyperbola method. The results indicate that the predicted curve is agree well with the field measurement curve below ultimate load; the hyperbola method is also suitable for squeezed branch pile; and the predicted results can be used in practice.
