摘要
对改建铁路襄渝线新七里沟隧道的膨胀土特性、膨胀土变形机制及变形规律进行研究与分析,形成了针对膨胀土隧道特点的施工技术,为同类地质情况下人工修建隧道提供借鉴与指导。
Through research and analysis on the features, deformation mechanism and deformation rules of the swelling soil in the rebuilding of Xinqiligou Tunnel on Railway Xiangyu Line, this paper sums up the construction techniques for swelling soil tunnels, and provides reference and guidance to the construction of tunnels under similar geographical situations.
