The combined model of reliability analysis for stability in gravity dam

In these factor which influence the stability of gravity dam, the random factor and the bounded factor of uncertainty often exist at the same time, the situation which can not be adapt if we introduce to single analysis model. So we proposed the ideas and methods that build the analysis model which combine the probability with non-probability to evaluation of stable reliability for gravity dam. And using the combined model evaluate the stable reliability of a gravity dam, which demonsrate that the combined model can better adapted evaluation of stable reliability for gravity dam than another model.
