Back analysis of earth rockfill dam's seepage property based on cloud reasoning
Liwei Han, Zongkun Li · 2010
For the aim of reflecting the randomness, fuzziness and the relevance between the two existed in the back analysis of earth rockfill dam's seepage property, by assumption of normal cloud distribution of the seepage parameter, a new back-analysis method based on cloud reasoning is presented in this paper. The method hangs together the uncertainty and reasoning, which is a think process that starting from the uncertain initial evidence, using the uncertain knowledge, and the reasonable conclusion with a certain degree uncertainty was deduced finally. At last the method was applied to the back analysis of a dam's seepage property, and the result shows that the application is feasible.
