We carried out a theoretical investigation of the nonlinear 
mechanism of nonperiodic motion in a saturated porous medium 
under the prolonged action of elastic waves.  Within  the 
framework of a generalization of the Frenkel-iot-Nikolaevskii 
model,  we  suggest  a  technique  for constructing a slow 
(background) solution that takes into account the accumulating 
effect of fast nonlinear oscillations.
