HydrologyHydrology

High groundwater levelStream at the surfaceLinks with deep thermal sources

Abundant presence of clay in the fault gouge due to an old thermal water circulation over the fault plan

>>> Fault zone has a low permeability and saturated soil

Engineering aspectEngineering aspect

Very bad rocks and low depth excavation (~15 m)

High risk of overexcavation and cave-in Important settlements at the surface High risk of water infiltrations Living area above the tunnel

Interception of the geological structure producing thermal sources

Risk of important modification of the aquifer

SolutionsSolutions Water Pumping from experimental gallery and 5

water wells to drain groundwater

No infiltration during tunnel excavation

Realization of a concrete trench to protect and divert the stream

Environmental protection

Jet grouting from the surface and the TBM

Reinforcement of the soils : better mechanical properties allowing excavation

Constant speed and medium pressure of the TBM cutting head applied on the rock face
