| Abstract: | The idea of maintaining groundwater environmental balance is used to design the tunnel under high hydrostatic pressure. The parameters of tunnel water handling and the method of calculation of lining against water pressure are studied. In the end, the method of design is introduced with Lishuwan Tunnel as a example. The construction results show that the idea of groundwater environmental balance applied to design the tunnel under high hydrostatic pressure is rational,safe and effective for environmental protection,cost reduction,reduction of construction time. |
