Triaxial creep test and model study of red sandstone based on Weibull distribution
Shuiwen dizhi gongcheng dizhi, 2023 At present, the creep problem of underground engineering surrounding rock still exists, and the creep theory needs to be further enriched. In essence, rock creep is a process of constant accumulation of damage.

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.
