The SRM method is based on the … Nettet30. jun. 2024 · In this research, a synthetic rock mass (SRM) numerical method is applied for characterizations of the jointed rock mass and excavation damage zone (EDZ) near underground tunnels in 3D. The SRM model consists of bonded particles and simulates deformation and crack propagation of the rock mass through interactions …
Nettetattempt to quantify the size effect in rock masses by synthesising the ensemble behaviour from the known behaviours of the components (joints and intact rock), which may be tested at small scale. This numerical scheme is known as the synthetic rock mass (SRM).

Nettet1. feb. 2011 · Rock mass classification (RMC) systems were developed for use in civil and mining engineering in response to the need for ways to “rank” a specific rock mass, … Nettet1. jul. 2008 · This paper uses numerical limit analysis to produce stability charts for rock slopes. These charts have been produced using the most recent version of the Hoek–Brown failure criterion. The applicability of this criterion is suited to isotropic and homogeneous intact rock, or heavily jointed rock masses.
NettetAs these developments represent a significative advance for mining geomechanics, this paper focuses on the application of the relatively recent 3D particle flow code (PFC3D) using the synthetic rock mass (SRM) approach to simulate the mechanical behaviour of not only intact rock, but also rock masses. In this approach, rock mass samples are ...
