Plastic zone range of a roadway considering the creep effect

Plastic zone range of a roadway considering the creep effect

Abstract The plastic zone range is an important parameter in the analysis of damage characteristics and the degree of damage to the rock surrounding a roadway. Based on the establishment of a plastic zone calculation model considering the creep effect, this paper obtains the characteristics of the c...
