Bit climbing method is introduced into genetic algorithm (GA) to improve generalization ability
calculating speed and precision of GA. Then this improved GA is used to identify the rheological parameters for materials of high rockfill dam with core wall of Nuozhandu Hydropower Station. Rheological parameters of various dam materials in different holes are identified
and the calculating results using the identified parameters perfectly agree with the tested data. Results also show that rheological parameters of different dam materials greatly differ from each other; so systematic experiments for all the dam materials are necessary. Also
there are some differences among rheological parameters of different dam materials
which may mean that various confining stresses influence the structure of dam material differently.
