从韩国和国外的铁路隧道防灾标准中特别值得注意的是，为了快速疏散，对疏散通道的设置采用了更严格的标准，这需要很高的成本。韩国标准规定，通道安装应根据风险水平，通过对每条长度为1公里或更长的隧道进行QRA分析来确定。然而，由于没有详细的应用标准，如火灾发生概率、火灾发生情景、火灾大小和社会风险水平的评估标准，可能会因过度设计而产生额外费用。因此，需要建立适当水平的标准。在此背景下，本研究通过对相关文献的研究和分析，选择了合理、适当的详细应用条件，分析了疏散通道或主要疏散促进设施的应用可以放宽的隧道最大长度，并对不同隧道长度的模型隧道(高铁)进行了QRA分析。此外，还编制了包括HONAM高铁在内的隧道的QRA结果和模型隧道的分析结果，并将最终结果与韩国和其他国家关于疏散促进设施的标准进行了比较，从而审查了应用标准的适宜性。这些成果预计将被用作制定合理的防灾计划的基本材料，该计划将考虑到安全和经济。
What is particularly noteworthy from Korean and foreign railway tunnel disaster prevention standards is that for the sake of rapid evacuation, more stringent standards for provision of evacuation passages, which require high cost, are being applied. Korean standards stipulate that passage installation should be determined in accordance with the level of risk through a QRA analysis of each tunnel with 1km or longer length. As, however, detailed application criteria as fire occurrence probability, fire occurrence scenario, size of fires and evaluation criteria for level of social risk are not available, additional costs may be incurred due to excessive design. Thus, standards of an appropriate level need to be established. With this backdrop, this study selects detailed application conditions of a reasonable and appropriate level through a study and analysis of relevant documents and analyzes the maximum length of tunnels to which the application of evacuation passages, or the application major evacuation promotion facilities, can be relaxed, together with a QRA analysis of model tunnels (for high speed rail) with different tunnel lengths. In addition, the QRA results on tunnels, including those on the Honam high-speed rail, and analysis results for the model tunnels, are compiled, ; the ultimate results are compared with Korean and other countries’ standards related to evacuation promotion facilities, As a result, The appropriateness of application standards are reviewed. These results are expected to be utilized as basic material for establishing a reasonable disaster prevention plan that will consider safety and economies.
