Upon the differential equation of pile deflection, the interaction problem of multi-layered soil and lateral-ly-loaded pile with different top restriction is studied. The deformation of the pile is closed with Fourier Series accompanied by additional terms. The analytical procedure of the problem is presented. The results of several numerical examples are compared with those obtaimed by FEM and field measurements.
Keywords: laterally-loaded pile; multi-layered soil; interaction, fourier series
