Abstract

A comparison of standard penetration test methods on bearing capacity analysis of shallow foundations on sand using analytical methods proposed by Parry, Meyerhof and modified Meyerhof has been carried out. The results showed three bound limits; upper, middle and lower bonds of net allowable bearing capacity, qn(a), values for isolated pad foundations placed on sand. Perry’s method gave higher values followed by the modified Meyerhof’s method and lastly by the Meyerhof’s method. Generally, qn(a) showed a decreasing trend as foundation breadth and depth increased. The qn(a) of modified Meyerhof’s model can be approximated by applying a factor of safety, FS, of 3.25 on Perry’s model. Similarly, qn(a) of Meyerhof’s model can be approximated by applying a factor of safety, FS, of 2.0 on the modified Meyerhof’s model.
