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 rock masses but only few of them can take into account the influence of the pre-existing natur...

To understand how long-range patterning gradients are interpreted at the cellular level, we investigate how a gradient of expression of the Four-jointed kinase specifies planar polarised distributions of the cadherins Fat and Dachsous in the Drosophila wing. We use computational modelling to test different scenarios for how Four-jointed might act and test the model predictions by employing fluo...

The presence of complex discontinuity patterns, the inherent statistical nature their geometrical parameters, uncertainties involved in estimation and geo-mechanical properties three dimensional (3-D) in-situ stress make accurate prediction rock mass strength a difficult task. It has been great challenge for mechanics engineering professions to develop criterion dimensions that incorporates eff...

In the construction project, rock mass is often destroyed from joint plane, and jointed easy to be eroded by freeze-thaw environment. Therefore, damage mechanical properties of filled under action are very important for disaster prevention, engineering safety evaluation reinforcement. order research effect cycle on deterioration characteristics rocks, prefabricated samples tested with different...
