Background Rock slope instability is a complex geotechnical issue that is affected by site-
specific rock properties, geological structures, groundwater, and earthquake load conditions …

Prediction of flyrock distance has a remarkable role in reduction and control of blasting
accident in surface mines. In this paper, at first a new empirical equation for predicting …

Among various engineering classification systems, RMR and GSI are two of the most widely
used rock mass classification systems. Correlation between RMR and GSI can provide an …

In this study a comparison of Discrete Fracture Network (DFN) modeling and empirical
relationships based on conventional engineering rock mass classifications is carried out in …

For deep large underground cavern projects under complex geological conditions, the
determination of rock mass mechanical parameters and stability analysis is fraught with a …

The discontinuity persistence is an important parameter that affects the strength of rock
masses and stability in rock engineering. However, determining the 3D discontinuity …

Rockburst (RB) is known as one of the deadliest and most destructive geotechnical events in
deep underground spaces under high stresses. The complexity of the RB phenomenon and …

Tunnel excavations in heavily fractured rock masses are often subjected to the high risk of
face instability. To solve this problem, the probabilistic stability analysis of tunnel face is …

The elastic modulus of rock is the key parameter in excavation deformation prediction,
support design, and the stability analysis of underground engineering. However, traditional …

In situ stress is an important parameter in rock mechanics, but localised measurements of
stress often display significant variability. For improved understanding of in situ matrices that …
