| Abstract: | Kuangjia 1# tunnel is a separation type of one-way driving tunnel. The paper discussed the design and construction of biased pressure compound lining for V-grade surrounding rock at the tunnel portal, open tunnel subsurface excavation, half light and half dark and so on; and put emphasis on discussing the engineering experience of crossing shallow embedded under biased pressure section at tunnel portal with construction scheme of open tunnel subsurface excavation and half light and half dark. |
