    abstract = {The present study, with the aim of applying the
principles and criteria of the linear elastic fracture
mechanics has investigated crack propagation in the body
and foundation of a concrete gravity dam under the worst
loading condition including the extraordinary loading
caused by the occurrence of earthquake under full
reservoir conditions. Based on the results of the analysis
of fatigue crack growth in different areas of the dam, the
maximum crack length is related to the area around the
upper gallery, the right side of the dam and the right wall
of the tunnel and in the horizontal direction. Further, the
maximum amount of crack growth is related to the
vertical direction and is equal to 3.15 m which has
occurred under model No. 6 related to the middle of the
upstream wall of the dam and the area behind the lower
gallery. The results demonstrated that the amount of
toughness is 2.36 in all submodelsand only in submodel
No. 12, the amount of toughness equals 1.29. The stress
coefficients calculated by energy and CTOD methods are
not much different and in most cases, the amount of the
final stress intensity factor is higher in the CTOD method.
According to the obtained results and with regard
tomaximum stress intensity factors, critical areas in the
dam were relatively identified to be the submodel of the
dam-foundation joint, submodel of the area around the
lower gallery in the middle of the upstream wall of the
dam, submodel of the area around the lower gallery, the
right wing and the left wall of the tunnel, submodel
ofcracks in the stone foundation and submodel ofthe area
around the lower gallery, the left wing and the right wall
of the tunnel.}
