Abstract: |
The planned tunnel alignment of the Brenner Base Tunnel crosses the aquifer of the Hochstegen marble between the Valsertal and Pfitschtal valleys. Due to the great importance of this aquifer for the water balance of the affected gullies, a 2D model was produced of the groundwater flow system. The intention of the 2D model was on one hand to gain information about the effects of the lowering of the groundwater table by the draining effect of the tunnel holes. Another intention of the model was to investigate whether the lowering of the groundwater table could be kept to a small and acceptable extent through a suitable grouting campaign and thus keep the influence on the groundwater balance in the model area small. |
