Abstract：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.
