某铁路双线黄土隧道塌方综合处理技术

Comprehensive collapse processing technology of the railway double-line loose tunnel

以某铁路双线黄土隧道工程为例,在深入分析隧道塌方成因的基础上,提出了以拱部帷幕注浆、大管棚刚性支护为主要措施的综合处理技术方案,安全、快速完成了塌方整治处理工作,为类似隧道塌方处理积累了经验。

With the collapse of loess tunnel of a railway line as an example,based on in-depth analysis of the causes of tunnel collapse,propose the arch of curtain grouting,the rigid supporting pipe shed for the main measures of comprehensive treatment scheme,safety,rapid completion of the collapse treatment,which can accumulate experience for similar tunnel collapse treatment.
