Nonlinear Numerical Simulation for the Concrete Zone of Fracture in the Process of the Developing Load at Soft-Rock Roadway

Inducting rupture mechanics principles, comprhensive research on the inside of stress distortion and its mechanism has been developed at auxiliary concrete structures roadway. Both situation result and resemble simulacruxn ending, the property parameters of support material have been identified. It is boortan to design, reinforce, enhance the strata cohesion in practical project.
