Development of Equivalent Stress- and Strain- Dependent Model for Jointed Rock Mass and Its Application to Underground Structure

Current design methods for underground structures surrounded by jointed rock masses fail to account for the deformational characteristics of these surrounding rock masses, employing only input parameters that are defined prior to construction. Thus, there is the need to investigate the effects on underground structures that result from the deformational characteristics of jointed rocks that undergo stress relaxation during their excavation....
