隧道软弱围岩大变形分析及治理措施
|
摘要
由于近年来铁路建设的重心从东部地区转移到西部,边疆多山地区的隧道建设越来越多,其中软弱围岩大变形的防治仍是工程界重难点问题。依托在建某隧道工程,通过对监控量测数据从时间效应和空间效应两个方面分析某隧道软弱围岩变形特征,总结大变形的影响因素,提出软岩治理措施,供该地区后续软岩段施工参考借鉴。
In recent years, the focus of railway construction shifted from the East to the West,tunnel construction in frontier mountainous regions more and more, the large deformation in the soft rock of the circles of control engineering is still heavy and difficult problem. Relying on a tunnel project under construction, through the analysis of monitoring data, from the two aspects of time and space effect analysis of a tunnel with weak surrounding rock deformation characteristics, summarizes the influencing factors of large deformation, put forward the control measures of soft rock, for the region subsequent soft rock section of construction for reference.
