- 摘要:
- 某油库扩容改建中发现，铁路正线与现有油库的安全距离不能满足《铁路运输安全保护条例》相关规定迫切需要采取有效措施，确保铁路运输安全和油库的正常扩容生产。通过对池火灾和爆炸性蒸汽云的研究，对油库槽车或油库罐区的危险性进行定量分析。结果显示在不设置任何保护措施的前提下，油库或槽车的火灾爆炸事故会对铁路正线的安全运行造成危害。防爆墙的应用则能有效削减火灾爆炸事故对铁路运输安全的威胁。分析计算表明，等效水平荷载按4 t/m2考虑时，具有特殊构造的防爆墙可发挥最优化功效。此研究结论对解决类似问题具有参考意义。
It is found during oil depot expansion reconstruction that there is serious nonconformance of safe clearance between railway trunk line and the existing oil depots with relative requirements specified in Regulation on Railway Transportation Safety Protection （Decree No. 430 issued by the State Council of the People’s Republic of China on December 27， 2004） and it is especially imperative to develop some corresponding effective measures in order to ensure railway transportation safety and necessary expansion reconstruction of oil depots in both sides of railway trunk lines. Researched are pool fires and explosive steam clouds formerly occurring in a certain oil depot tank lorry or oil tank farm and quantitative analysis is conducted on their risks. The analysis results show that fire and explosive accidents in oil depot tank lorry or oil tank farm will result in serious hazards on local railway transportation safety in the absence of any protective measures. Construction of an explosion-proof wall around oil depot can effectively reduce risks of such accidents on railway transportation safety. Calculation results show that a specially structured explosion-proof wall with a horizontal equivalent load of 4t/m2 will have optimum efficacy for railway transportation safety protection， which can provide important reference for solving similar issues in future.
