摘要
张集铁路旧堡隧道穿过古老的太古界变质岩地层,地质复杂,围岩软弱,多次发生突水突泥,使支护受到破坏,施工长时间受阻。通过采用"泄水降压、注浆加固、管棚支护、两端夹击"的治理原则和有效的施工方案,使隧道安全顺利贯通。
The Jiubao Tunnel passes through old Archaeozoic metamorphic strata with complex geology and soft surrounding rocks.During tunnel construction,mud and water outbursts were encountered several times resulting in damaged supports and delays to construction.The treatment principles of ＂pressure reduction by water discharging,grouting reinforcement and pipe-roofing support＂ and relative construction measures were adopted to make construction of the tunnel safe and efficient.
