摘要
通过对某铁路纵目沟隧道西安端浅埋偏压段的处理,着重介绍了地面注浆加固、超前管棚及锁脚钢管的施工工艺,分析各影响因素与拱顶沉降与地表下沉的关系,优化了施工方案。
The construction technology of ground casting reinforcement,forepoling pipe-shed and steel foot pipe is introduced in detail,the relations between the influencing factors and the tunnel settlement and surface subsidence are analyzed and the construction scheme is optimized through the treatment for Xi＇an shallow-buried unsymmetrical loading section of one railway Zongmugou Tunnel.
