摘　　要：以新建兰渝铁路马家山隧道施工为例,介绍大断面隧道塌方处理施工方法。通过将监控量测与弱松动爆破相结合的方法,安全、快速处理塌方。并得出结论:有针对性的施工措施,确保了塌方处理的顺利进行,为大断面隧道塌方处理提供了一条思路。Taking Majashan tunnel construction of new Lanyu Railway as an example,the paper introduced the construction technology for treating collapse of large cross-section tunnel.By means of conjoining monitoring and measuring with weak loose blasting the collapse can be securely speedy deal with.Thus the paper concludes that taking targeted construction measures can insure smoothly treating collapse,and provides thinking for treating collapse of large cross-section tunnel.

关 键 词：塌方处理 监控量测 大断面隧道
