油库作为油品储存的主要场所，存储了大量易燃、可燃液体，这使得油库本身具有较高的火灾爆炸事故风险。为了防止火灾爆炸事故发生和降低事故后果严重程度，有必要对油库风险和事故后果进行分析研究，为油库安全措施制定与事故应急处置提供依据。宝鸡油库的危险物品主要为汽油和柴油，均为易燃液体。通过重大危险源辨识方法进行评估发现，宝鸡油库属于一级重大危险源。

通过对宝鸡油库个人风险和社会风险进行计算，发现个人风险和社会风险均存在不符合要求情况。其中个人风险中风险为3×10-5的风险等值线覆盖了部分胥家崖村的居民区，社会风险达到了不可接受风险。分别通过降低油库储量和人员搬迁的方法来降低个人风险和社会风险。结果表明，停用TG01储罐和将可能覆盖区域人员搬迁的方法可以将个人风险由不符合个人风险基准值要求降低到基本符合个人风险基准值，可将社会风险由不可接受区域降低到尽可能降低风险区域，个人风险覆盖区域搬迁人员越多，社会风险越小。

通过对宝鸡油库储罐、罐车和槽车进行事故后果模拟，发现泄漏孔径为5mm时，汽油储罐、罐车和槽车池火灾后期37.5kw/m2热辐射的半径分别为7.5m、4.5m和4m，均小于两个相邻设备之间的最小距离，这不会引起相邻设备的多米诺效应。当泄漏孔径大于5mm时，池火灾后期热辐射通量没有达到37.5 kw/m2，所以不会引起相邻设备的多米诺效应；当汽油储罐泄漏孔径为25mm和100mm、汽油罐车泄漏孔径为100mm以及汽油槽车泄漏孔径为100mm时，超过两个储罐、罐车和槽车之间的最小距离，在这些情况下发生喷射火时可能会引起相邻设备的多米诺效应；储罐、罐车和槽车在发生蒸汽云爆炸时，爆炸区域均不在罐区，所以不会引起相邻储罐发生多米诺效应；柴油储罐、罐车和槽车均不会发生多米诺效应。另外，储罐、罐车和槽车产生的爆炸冲击波以及产生的热辐射可能不会引起多米诺效应，但会对厂区工人及周边居民区人员造成身体伤害。不同事故后果产生的热辐射和爆炸冲击波等高线半径即为安全防护距离，当发生泄漏爆炸时，应将人群疏散至安全防护距离之外。最后计算了不同风速时的汽油储罐全破裂事故后果，发现随着风速（1m/s~1.7 m/s）的增加4 kw/m2的热辐射半径逐渐增大，爆炸超压半径先增大后减小，爆炸中心距泄漏点距离逐渐减小，而最大爆炸超压保持不变。

As the main place for oil storage, the oil depot stores a large number of flammable and combustible liquids, which makes the oil depot itself have a high risk of fire and explosion accidents. In order to prevent the occurrence of fire and explosion accidents and reduce the severity of the consequences of accidents, it is necessary to analyze and study the risks and accident consequences of oil depots to provide a basis for the formulation of safety measures and emergency handling of accidents in oil depots. The dangerous goods in Baoji Oil Depot are mainly gasoline and diesel, both of which are flammable liquids. Through the evaluation of major hazard identification methods, it was found that Baoji oil depot belonged to the first major hazard source.

Through the calculation of personal risk and social risk of Baoji oil depot, it is found that both personal risk and social risk do not meet the requirements. Among them, the risk contour line of 3×10^-5 in the personal risk covers some residential areas of Xujiaya Village, and the social risk has reached an unacceptable risk. Reduce personal and social risks by reducing oil depot reserves and relocating personnel, respectively. The results show that the method of stopping the TG01 tank and relocating personnel in the possible coverage area can reduce the personal risk from not meeting the requirements of the personal risk benchmark value to basically meeting the personal risk benchmark value, and can reduce the social risk from the unacceptable area to the risk reduction area as much as possible.

By simulating the consequences of accidents on storage tanks, tank cars and tank cars in Baoji Oil Depot, it is found that when the leak hole diameter is 5mm, the radii of 37.5kw/m² heat radiation in the late stage of the fire of gasoline storage tanks, tank cars and tank cars are 7.5m, 4.5m and 4.5m respectively. 4m, both less than the minimum distance between two adjacent devices, which will not cause a domino effect of adjacent devices. When the leakage aperture is larger than 5mm, the thermal radiation flux in the later stage of the pool fire does not reach 37.5 kw/m², so it will not cause the domino effect of adjacent equipment; when the leakage aperture of the gasoline storage tank is 25mm and 100mm, the leakage aperture of the gasoline tanker is 100mm and When the leakage hole diameter of gasoline tanker is 100mm, the minimum distance between two storage tanks, tanker and tanker is exceeded, and the domino effect of adjacent equipment may be caused when a jet fire occurs under these circumstances. When the steam cloud explosion of storage tanks, tank trucks and tank trucks occurs, the explosion area is not in the tank area, so it will not cause domino effects in adjacent storage tanks; diesel storage tanks, tank trucks and tank trucks will not have domino effects. In addition, the explosion shock waves and thermal radiation generated by storage tanks, tank trucks and tank trucks may not cause a domino effect, but they will cause bodily harm to workers in the factory and surrounding residential areas. The radius of the contour lines of thermal radiation and explosion shock waves produced by different accident consequences is the safety protection distance. When a leakage explosion occurs, the crowd should be evacuated beyond the safety protection distance. Finally, the consequences of the total rupture accident of gasoline storage tanks at different wind speeds were calculated, and it was found that with the increase of wind speed (1m/s~1.7 m/s), the heat radiation radius of 4 kw/m² gradually increased, and the explosion overpressure radius increased first After decreasing, the distance between the explosion center and the leakage point gradually decreases, while the maximum explosion overpressure remains unchanged.
