隧道穿越冲沟滑体加固设计方案研究

Design Scheme of Tunnel Passing Through Gully Slip Mass

分析某在建高速公路某隧道施工过程,该工程在隧道出洞时发生穿越冲沟,引起已建隧道洞项山体开裂,对隧道安全运营造成巨大隐患。设计中对未施作隧道进行加固设计及对洞口附近小滑体进行整治,以确保隧道施工及运营安全。

This paper analyzes a tunnel of a highway under construction.Crossing gully has happened in the project when the tunnel was unkenneling which caused tunnel roof mountain mass′ cracking.It has a huge risk about the safety of the operation of tunnel.In order to ensure the safety of the construction and operation of the tunnel,the tunnel which has not been constructed is reinforced in design and the small slip mass near cave is treated.
