黄土公路隧道塌方风险事故树探析

Accident Tree Analysis on loose highway tunnel collapse risk

针对黄土公路隧道塌方问题,从地质、设计、施工等方面入手,分析了隧道塌方的原因及发生机理,采用事故树分析方法,确定了塌方发生的主要诱导因素,为今后黄土隧道塌方分析提供了参考依据。

In light of loose highway tunnel collapse problems,starting from aspects of geology,design and construction,the paper analyzes tunnel collapse causes and mechanism,applies Accident Tree Analysis method,and determines major collapse inducing factors,which has provided some guidance for loose tunnel collapse analysis in future.
