| 摘 要： | 以兰渝铁路胡家湾隧道进口段施工为例，介绍泥岩地层修建大断面隧道变形控制的方法。施工中通过围岩量测掌握围岩变形动态，采取分部开挖临时仰拱封闭成环及上半断面扇形支撑的技术措施，控制围岩的变形。实践证明:效果较好，对目前的客专大断面隧道控制大变形施工有一定的帮助。

| Abstract: | The deformation control method for large cross-section tunnels in mudstone ground is presented,with the construction of the entrance section of Hujiawan tunnel on Lanzhou-Chongqing railway as an example.During construction,monitoring is executed to master the status of the rock mass deformation and temporary inverts and fan-shaped supports are installed for the tunnel constructed by top heading and bench method so as to control the deformation.In the end,satisfactory results are achieved.The paper can be se... |
