摘要
以大广高速公路象形2#隧道为例,对隧道塌方原因进行了分析,制定相应的措施,成功处理塌方空腔段。总结施工经验,旨在为同类围岩隧道施工提供参考。
Taking 2# pictographic tunnel of Daguang expressway as the example, the reasons for tunnel collapse are analyzed, and corresponding measures are taken to successfully treat the section of collapse cavity. The construction experience is summarized, so as to provide reference for similar construction of tunnel with surrounding rock.
