... changed. And we have to design the refracturing scheme according to the new stress field. Using the boundary element method to calculate the crack propagation induced stress field in the multi-stage acid pressure process, we can determine the size of the stress shadow, and whether the subsequent crack can...

... Abstract A hybrid finite-discrete element method is introduced to simulate dynamic fracture of rock and resultant fragment arching caused by rock blast. Three typical examples, i.e. blast in a rock mass with a single borehole and a free surface, simultaneous blast, and consecutive blast...

... ABSTRACT Evidence of a complex failure mechanism which involved both a distinct planar sliding surface, in addition to block-flexural toppling has contributed to the instability at a UK slate quarry. The failure was investigated using the Discrete Element Method (DEM) and the Finite Element...

... ecological balance. Keywords: Dump stability, Discrete Element Method, PFC 2D, Bio-stabilisation 1. INTRODUCTION Slope stability is a prime concern in both natural and man made slopes. It is critical because slope stability influences the economics of such projects in direct or indirect ways (Singh et.al...

... and reinforcement and their response through numerical modeling. In this study, several simulations have been done to understand the effect of excavation for tunnels on a soft ground through numerical modeling by discrete element method (DEM). The numerical simulations adopting discrete element method predicts...

... are essential. On account of these facts, at the first stage, practical methods were chosen to provide proper and reasonable supporting systems to meet the stability of the tunnels. At the second stage, two-dimensional static distinct and finite element methods were collected to perform static analysis...
