Propagation Law of Cracks in Surrounding Rock of Different Shape Tunnels Under Adjacent Blasting
To understand the effect of the tunnel section shape on the crack propagation law of surrounding rock in adjacent tunnel under blast loading, detailed research is carried out by model test and extended finite element(XFEM). The experimental study shows that under the blast loading, when the original...
