It is important to understand the hydraulic properties of rock mass for rock engineering projects such as dam foundation grouting and nuclear waste disposal. For a fracture-dominant rock mass, the flow paths of the groundwater are dominantly controlled by the distributions and connectivity of the permeable fractures.
My research focuses on the use of the DFN (Discrete Fracture Network) approach, which models the fractures stochastically based on the statistical distribution of the fracture properties. The research also extends to the numerical simulation of grouting in rock mass for ground improvement and reduction of permeability.
My research topics include the followings;
- Development of DFN modeling methodology from field data,
- Evaluation of hydraulic properties of rock mass from DFN models,
- Numerical simulation of grouting in a single discontinuity and fracture network system.
