| 中文摘要:通过宜昌市北海路隧道塌方处理施工的实例，分析了造成塌方的原因，提出并实施了钢拱架、锚喷网复合支护结构塌方处理方案，并对塌空区的回填方案进行了比对，优选泵送陶粒砼加固的新工艺，取得了较好的回填加固效果。通过监控量测成果分析证明了采用陶粒砼工艺大大减轻了回填砼的质量，从而减小了对钢拱架支撑、锚喷复合支护结构的压力，确保回填砼及钢拱架支撑、锚喷复合支护结构的稳定性，确定二次砼衬砌施作的时间。 |

| Abstract:The cause of collapse was analyzed by tunnel collapse in Beihai Road in Yichang City, the treatment by steel arch frame and composite support with bolt shotcreting mesh was introduced. Better result of backfill was achieved by argil concrete that is light to reduce the loading supporting structure. |
