隧道初期支护

Primary Support of the Tunnel

随着我国交通建设的快速发展,地铁、铁路等施工项目越来越多,使得隧道施工变得很重要。初期支护在隧道施工中占据着重要的角色,应加强隧道初期支护施工技术。杨家庄隧道工程地质复杂、工期紧张、施工条件恶劣,本文对该隧道的初期支护施工技术进行介绍,给类似工程施工提供了参考依据。

With the rapid development of transportation construction, the number of underground and railway construction projects is increasing, which makes tunnel construction become important. Primary support plays an important role in tunnel construction, and primary support construction technology should be strengthened. The geology of Yangjiazhuang tunnel engineering is complex, time is limited, and condition is harsh. This paper introduces the primary support construction technology of the tunnel, and provides references for similar project construction.
