Estimation of Rock Fracture Properties from Thermal Variations of the Groundwater Discharge Into a Tunnel
Original language description
Paper in proceedings without ISBN on memory medium 8 pages: We study the coupled water flow and heat transport (conduction and advection) in a neighborhood of a tunnel in fractured granite (in up to 150 m depth in Jizera mountains, Czech Republic). The temperature in the tunnel changes quasi-periodically in the annual cycle, affecting the rock temperature and the discharge water temperature. This is captured by an axisymmetric model of a fracture perpendicular to the tunnel (with advective heat transport) and a surrounding matrix block with conduction only. The model is successfully fit to measurement and some of the parameters or features not specified from the measurement and from the hydraulic model can be estimated. On the other hand, due to modelsimplification, it is sensitive on an artificial parameter which has not a realistic counterpart (a gap in the boundary condition).
