摘要
文章通过公山隧道贯通段塌方处理技术的实例,从大断面隧道贯通段塌方的原因分析,介绍了隧道塌方的处理方案、施工工序等施工技术。由于本次隧道贯通段塌方的处理采取厂有效方案,保证了施工安全,处理过程中没有出现二次塌方和掉块现象,围岩和结构处于稳定状态,达到了预期的"安全、稳妥、保质、经济"的目的。其成果可供类似隧道的塌方处理参考、借鉴。
Using the Gongshan tunnel as an example, this paper introduces the construction technique for treating a collapse at the tunnel breakthrough in terms of cause analysis, treatment schemes, and construction procedures. No further collapsing or rock failing occurred during construction treatment, and the surrounding rock and strueture remained stable, realizing the goals of safe, reliable, qualified, and economic construction
