摘要
塌方是地下工程易出现的工程事故,如何有效处理塌方是亟待解决的难题。根据某灌溉隧洞工程因发育断层破碎带而导致大塌方的处治实例,结合浅埋隧道塌方处治中超前支护系统的作用原理,讨论了塌方附近敏感段加固处理和"大塌穿、先护后挖"处理塌方的插圆木拱架法。
Based on an irrigation tunnel consolidation project,the mechanism of the pre-support system applied in treatment for the collapse of a shallow-buried tunnel are discussed. Then the strengthening technology of the landslides near sensitive handling and technology of inserted-hard-round-sticks and bent in collapse body consolidation are also discussed.
