Time-dependent mechanical behavior and support timing of surrounding rock governed by crack closure ratio

Abstract The long-term deformation characteristics of rock are crucial for ensuring the stability and safety of underground engineering projects. This study examines the time-dependent damage behavior of granite samples from the Shuangjiangkou underground powerhouse under creep loading, with a focus...
