Creep test and constitutive model for granite with different water content after high temperature cooling
Year: 2025
Type: article
Abstract: Granite was selected as the test specimen to carry out the rock triaxial compression creep test under different water content after high temperature cooling.The creep rate at low stress levels includes deceleration creep rate and steady creep rate.The new damage variable can not only describe the physical damage of the crack growth under the action of temperature, but also characterize the mechanical damage of the specimen under the action of loading.A new damage creep model was obtained by modifying the Burgers model.The research can provide ideas for the support of a high and steep slope.
