A new nine-parameter rheological constitutive model is applied to rheological analysis of Shuibuya Concrete Faced Rockfill Dam(CFRD)
rockfill body rheological mechanism is also discussed from the experimental viewpoint. The computed results show that the dam settlement duration curve which is based on 3-D simulation results is super accordant with the practical data. The results prove nine-parameter rheological constitutive model’s validity and feasibility.
