摘要
针对隧道施工中几种不同围岩条件下的初支结构侵限问题,介绍了两种主要侵限形式,并介绍了相应的处理措施,同时提出了几方面的预防措施。
Based on beyond limit of primary support structure under different surrounding rocks in tunnel construction,two main forms of beyond limit are introduced.Meanwhile,corresponding treatment measures are also introduced and preventive measures in different aspects are proposed.
