Tunnel Inflow in Granite - Fitting the Field Observations with Hybrid Model of Discrete Fractures and Continuum

Popis výsledku v původním jazyce

We study the water inflow into a tunnel in granite massif in Jizera Mountains, Czech Republic, 2600m long with 150m maximum depth. The dominant inflow occurs in the shallow parts and in few fault zones in the deep part. We use a combination of 2D discrete fractures and 3D equivalent continuum to model the flow around the tunnel in a kilometre-scale domain. We use the software Flow123D developed at our department. The geometry is based on the digital terrain model and the positions of faults determined by e.g. geophysical methods. The meshing was difficult due to a small scale of the tunnel and intersections with the fault planes. The inflow is measured as a flow rate in a collecting canal by either weirs or tracer dilution method, divided to five segments of the tunnel. We calibrate the hydraulic conductivities of upper weathered zone, lower compact massif, and the vertical faults, by fitting the inflow from these subdomains, using the inverse solver UCODE. The fitted hydraulic paramet
