Creep Rate and Creep Model of Rockfill
Procedia Engineering, 2012 AbstractDue to the test duration restriction, not only the creep strain but also the creep rate should be considered to establish the creep model of the rockfill. The creep rate decides whether the creep model deviates from the actual strain after the test duration.
