Resumen:

Results of penetration and pull out tests carried out on concrete piles driven in Mexico City clay show several significant characteristics of the friction pile behavior. First, the maximum penetration load capacity depends upon the rate of applied load, the higher the rate the higher the capacity. Second, the rate has also a similar influence on the mean slope of the load vs. displacement (P-d) curve. Third, friction pull out capacity attains a maximum value equal to the friction penetration capacity; even though, the extraction load vs displacement curve is different from the corresponding one in penetration. Finally, the parameter a used on bearing capacity of friction piles is found to be 1.2 for Mexico City clays.
