| 摘 要： | 隧道在施工过程中,由于地质不良、排水不畅、施工工艺不当等原因造成已经开挖部分隧道发生大的变形。工字钢变形、喷射混凝土开裂、净空收敛等现象,对隧道施工及将来运营产生一系列严重后果。本文通过对一典型隧道大变形进行处理,通过处理后满足设计、规范及运营需要。

| Abstract: | During the construct of the tunnel, because of the poor geological conditions, water, improper construction technologies and other reasons, excavated section of the tunnel was deformed greatly. Steel deformation, concrete cracking, clearance convergence phenomenon, etc., it will produce a series of serious consequences in the stage of tunnel construction and operation. Based on a typical tunnel, a deformation processing scheme was given to meet need of the design, specification and operation |
