A DFN-LiDAR-optical sensor method for the estimation of rockmass conditions in underground projects
Abstract: A sound and economical underground project design depends on a realistic geological model, a quality rockmass characterization and an informed assessment of other influencing factors. However, due to the lack of truly three-dimensional subsurface fracture geometry data, this reality is rendered difficult. In order to overcome this, the use of Discrete Fracture Networks (DFNs) is becoming...

DFN generation for Mechanical Stability Analysis of Underground Works
Abstract: A first step in the characterization of fractured rock materials and its anticipated mechanical response during an underground excavation is the static mapping and modelling of the subsurface fracture system. This task is rendered difficult by the lack of truly 3D data about the subsurface fracture geometry. Yet, it is critical to be able to establish a reliable, geologically and...

Temporary Tunnel Support Strategies: Optimization and Testing
Abstract: When designing and constructing support systems for tunnels in weak ground, oftentimes a temporary support regime is utilized in order to provide provisional support until the final liner is installed. These support systems are primarily designed contingent upon the ground conditions that are anticipated. The assortment and arrangement of such support systems are many and involve but, are not...
