Unloading-Induced Crack Propagation of Two Collinear Unequal Length Flaws in Brittle Rocks
The propagation and coalescence of numerous discontinuous joints significantly contribute to landslide instability during excavation unloading. The tip expression of stress intensity factors of two collinear unequal length cracks in a typical rock mass under unloading conditions was calculated based...
