This paper studies the stress of gravity dam heel with careful numerical simulation, and analyses the effect of the variety of the elastic modulus of homogeneous or non-homogeneous foundations on the principal tensile stresses of gravity dam heel. The conclusions are as follows:① When the elastic modulus of homogeneous dam base and variated element in the critical place is changed with the same the fluctuation, the effect on the dam heel stresses caused by the latter is much more prominent than the former one.
