摘要
介绍了阿家岭隧道在穿越既有铁路线施工中,采用沉降数据反馈,适时调整开挖参数的开挖方法,确保沉降数据在控制范围内,从而保证隧道开挖时不影响既有铁路线安全运行。该技术根据隧道独特的施工条件,突破常规施工方法和工艺,为类似工程施工提供了参考。
In the construction of Ajialing tunnel through existing railway, the method timely adjusting excavation parameter with subsidence data feedback was adopted to ensure that the subsidence data within the scope of control, thus the safety of existing railway is ensured not to be affected during excavating the tunnel. The technique is on basis of the unique construction condition of the tunnel with a breakthrough of general constructing method and technique, and offers a reference for similar projects.
