大管棚在厦门海底隧道不良地段施工中的应用

The Application of Pipe Sheds in Xiamen Harbour Crossing Adverse Construction of the Lot

厦门海底隧道右洞,穿越洞口浅埋地层、过环岛路土石交界、F1风化深槽不良地质段,采用管棚施工。阐述施作管棚工法,通过监控量测结果分析,总结超前预支护技术在通过不良地质段大断面隧道软弱围岩的作用。

Xiamen right-Harbour Tunnel, across the shallow hole formation, a roundabout at the junction of road debris, F1 deep weathered adverse geological, use pipe sheds construction methods, through monitoring the results of measurement, sum up security ahead of advances in technology through adverse geological cross-section of the tunnel the role of soft rock.
