The new K-G Model that considers the dilatancy and strain softening of soils and the widespread E-u model are applied to 2-D finite element aualysis of stress-strain of Zipingpu Concrete Faced Rockfill Dam. The result of the K-G model is compared with the results the E-u model and
3-D FEM stress-strain analysis of the dam and the prototype observations of the other built projects to obtain the stress-displacement law of the dam. The result of the settlement and level displacement of the dam applied the new K-G model is normal. Especially
the new K-G model is more rational than the E-u model at the side of the horizontal displacement. The results test and verify the new K-G model’s rationality initially.
