摘要
结合马鞍山隧道工程概况,分析了隧道存在浅埋偏压现象及施工中发生坍塌的原因,并从洞外处理、洞内初期支护处理和洞内坍塌体处理三方面确立了塌方处理施工方案,成功治理了隧道坍塌并顺利通过坍塌区域。
Combined with general engineering situations of Ma' anshan tunnel the shallow cover and lateral pressure situations of this tunnel and reasons caused the collapse of tunnel are analyzed,at the same time from three aspects: outside treatment, primary support and collapee body treatmoat in tunnel practical collapse treatment scheme is determined, which realize successful treatment of collapse ensure nomal running of railway line.
