地下水环境平衡的理念在高水压隧道设计中的应用

将维持地下水环境平衡的设计理念应用于高水压隧道的设计中。对设计中防排水参数和抗水压衬砌计算方法进行了探讨。以梨树湾隧道为实例介绍了具体设计方法。该隧道施工结果表明：应用地下水环境平衡的理念设计高水压隧道，对于保护环境、降低隧道造价、加快施工速度都是合理、安全和有效的。

The idea of underground water environmental balance applied to the design of the tunnel under high hydrostatic pressures

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.
