Design groundwater of rock tunnel
Design groundwater of rock tunnel
(OP)
Dear all,
I am preparing a rock tunnel lining design. The tunnel is proposed to be drilled through hilly region which is far above the sea level. I think the groundwater in rock is mainly come from rainfall.
As it is a preliminary design, no groundwater monitoring is carried out. I assume a design groundwater table of 10m above the lining in this assignment. Is there any reference to assign the design groundwater table in rock tunnel?
Thanks

(1) What is the next step to predict the inflow in rock during tunneling? I know there is a IMS system to predict the water inflow. Another common methods or key parameters required to predict the water inflow?
(2) Any reference/ suggestion on permenant drainage system for a lined deep rock tunnel by TBM?
Thanks
