摘要： 通过某隧道塌方事故处理，介绍了一种先对塌方段减载、明挖、再施工洞内二次衬砌到临界塌方体处、然后从明挖段重新进洞的黄土隧道塌方事故处理方案；并分析得出导致发生塌方事故不仅有工程地质的主观因素，还有人为安全意识差等客观因素。以供类似隧道施工及处理塌方事故借鉴应用。

Abstract: This paper presents a case study of mitigating a collapsed tunnel. At the collapsed area, the open excavation and unloading were first performed followed immediately by the installation of the tunnel liner. When the reconstructed tunnel was past the distressed area, the original tunneling method could be resumed. The paper also analyzes the possible factors that could contribute the collapse. In addition to the adverse subsurface conditions, the safety alert level among the construction personnel may also be the problem.
