凉风坳隧道位于株六复线D标段,隧道通过地段多为页岩,节理裂隙较发育,并且通过一断层及断层破碎带、滑坡体。本文介绍了凉风坳隧道软弱围岩下施工技术及其过断层、断层破碎带、滑坡体等不良地质地段的施工措施。对今后类似工程的施工是一个良好的借鉴。
The Liangfengao Tunnel is located on the D section of the Zhu-Li-Shuang-Shuang line. Most of the tunnel passes through the site are mostly shales. The joints and fractures are well developed, and the landslide body passes through a fault and fault-broken zone. This article introduces the construction techniques of the weak surrounding rock of Liangfengga tunnel and its construction measures such as fault, fault zone and landslide. The construction of similar projects in the future is a good reference.
