Fly Ash has been used for many years in geotechnical engineering. A research has been carried out to examine the stress-strain behaviour of fly ash, applied within two existing finite element programs. In the first program, undrained triaxial tests are simulated at a pressure of 100 kPa, and two cases are observed, that are dilatant and non-dilatant. Both cases show similarity in the results with the experimental in the elastic region for ?3 = 100 kPa. For the dilatant in the plastic region, the result has a higher value of deviator stress than the experimental. While for the non-dilatant, the result has a lower value. Another program is carried out to calculate the maximum displacement versus safety factor for the clay slope and an alternative solution using fly ash. The results show that the most significant impact was obtained when fly ash is used to re-construct the clay slope, in which the displacement is reduced.
