Study on Longitudinal Deformation Analysis and Support Technology of Surrounding Rock in Roadway Excavation

To study the influence of excavation space effect on roadway excavation, Hoek’s displacement coefficient equation is used to describe the longitudinal deformation law of roadway surrounding rock under the spatial effect, and the relationship between the radial displacement of the roadway and the vi...
