Estimation of In-Situ Block Size Distribution in Jointed Rock Masses using Combined Photogrammetry and Discrete Fracture Network

M. Ghaedi Ghalini; M. Bahaaddini; M. Amiri Hossaini

Volume 13, Issue 1 , January 2022, , Pages 175-184


  Estimation of the in-situ block size is known as a key parameter in the characterization of the mechanical properties of rock masses. As the in-situ block size cannot be measured directly, several simplified methods have been developed, where the intrinsic variability of the geometrical features of discontinuities ...  Read More

Rock Mechanics
Discrete element modeling of explosion-induced fracture extension in jointed rock masses

M. Lak; M. Fatehi Marji; A.R. Yarahamdi Bafghi; A. Abdollahipour

Volume 10, Issue 1 , January 2019, , Pages 125-138


  The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures ...  Read More

Rock Mechanics
Stability analysis of support systems using a coupled FEM-DFN model (Case study: a diversion tunnel at Lorestan dam site, Iran)

M. Noroozi; R. Rafiee; M. Najafi

Volume 9, Issue 2 , April 2018, , Pages 485-497


  Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed ...  Read More
