Deformation Analysis of the 233 m Shuibuya Rockfill Dam Using Breakage Mechanics
Time-dependent deformation is a major concern for the design and operation of rockfill dams. Meanwhile, the scaling between the stress-strain behavior of the reduced specimens for laboratory tests and the prototype rockfills for dam constructions has not been appropriately emphasized nor yet to be addressed. The recently developed rate-dependent breakage mechanics model is integrated here with the fracture-mechanics based scaling law to predict the long-term deformation of rockfill dams. The predictive capacity of this new method is evaluated through a comprehensive case study on a 233 m concrete face rockfill dam (CFRD), the Shuibuya CFRD. We show that the proposed model can predict reasonably well the settlement response across a long-time span from construction to operation stages. The horizontal displacement, stress contours, and breakage distributions are also presented for analyzing the global response of the Shuibuya CFRD and the evolution of its internal gradations.
