Paper Title:
Research into the Influence of Dam Material’s Rheology on Stress and Deformation of a High CFRD
  Abstract

Existing research results have indicated that dam material’s rheology under a high stress state is quite evident. In order to study the influence of dam material’s rheology on the stress and deformation of a CFRD, a nine parameter power series rheology model is adopted to analyze the stress and deformation of a high CFRD considering the dam material’s rheology. Calculation results show that since an obvious increase in dam body’s deformation occurs after considering the rheology characteristics of rock-fills, dam body’s stress tends to relax. Rockfill’s rheology characteristics increases the deflection of a face slab to a certain degree, face slab’s slope and dam’s axial maximum tensile stresses rise somewhat as well. As for a high CFRD that face slabs are placed in stages and water impounds in stages, a proper rheology constitutive model is adopted to correctly simulate rock-fill’s rheology characteristics, and results from this modeling can be used for reference for the determination of dam’s filling schedule and face slab’s staged placing and have important meaning for correctly predicting dam’s stress and deformation.
