Summary:
This paper presents an exact solution for the load - settlement relationship of axially
loaded piles embedded in nonhomogeneous elastic foundation. The governing differential
equation is reduced to modified Bessel equation of order v. The solution is represented by
Bessel's functions of the first kind of order v. The stiffiiess coefficients are then derived
from the exact solution. Numerical comparison with approximate solutions of special
cases verify the accuracy and efficiency of the adopted method.
