| Abstract: | In this paper, Taylor unfolding stochastic finite element method is studied. The partial derivative matrix of stress is developed by combining the random feature of the variables for the equal parameter element with eight noodle points. In the example, the reliability of a gravity dam and the effects of reliability on the elastic modulus of foundation are analyzed. |

| Keywords: | stochastic finite element reliability gravity dam elastic modulus |
