摘要
针对苦致山隧道坍方段围岩的特点,采用了回填混凝土治理的方案,为隧道施工安全、施工工期提供了保障,其经济效益和社会效益比较明显,可供同类工程实践借鉴参考。
Concrete back - filling is carried out in Kuzhishan tunnel to treatment the collapse according to the specific condition of surrounding rock at the collapsing section, which assures the safety and construction period of tunnel. Furthermore it is significant in terms of economic and social benefit. Reference can be taken from this by the similar projects in the future.
