摘要:

为响应我国“十四五”规划中对清洁能源提出的要求,使我国城镇燃气管道安全管理水平适应发展的需求,从生命风险的角度研讨城镇燃气管道风险可接受标准。首先采用平均个人风险(AIR)法和最低合理可行(ALARP)准则相结合的方法,统计2012—2021年的事故数据;然后以5年为一周期进行对比分析,以上一个5年周期的风险可接受标准预测下一个5年周期的风险可接受标准参考值,并得出2022—2026年个人风险可接受标准的参考值;最后依照在个人风险可接受标准 5年周期预测法,采用累计频率-死亡人数(F-N)曲线法,统计2017—2021年每起事故死亡数及年管道长度,并确定社会风险可接受标准。研究表明:以风险水平1.017 13×10-7作为个人风险不可接受风险区与ALARP区分界线,2.034 27×10-7作为ALARP区与可接受风险区的划分边界;同时确定了社会风险最大可接受风险曲线和可忽略风险曲线,并结合ALARP准则划分出风险区域。

Abstract:

In respond to the higher requirement for clean energy put forward by the 14th Five-Year plan, the risk acceptable criteria of urban gas pipeline were studied from the perspective of life risk, in order to make the safety management level of urban gas pipeline can meet the needs of development. The accident data of 2012-2021 were counted by combining average individual risk (AIR) method with ALARP criterion, and the risk acceptable criteria of the previous five-year cycle were used for analysis and comparison. The reference value of the risk acceptable criteria of the next five-year cycle was predicted by adopting the risk acceptable criteria of the previous five-year cycle, and the reference value of the acceptable criteria of individual risk from 2022 to 2026 was obtained. According to the five-year cycle prediction method discussed in the individual risk acceptable criteria study, the F-N curve method was used to calculate the number of deaths per accident and annual pipeline length from 2017 to 2021, and the societal risk acceptable criteria was determined. The study shows that the risk level of 1.017 13×10-7 is the boundary of the unacceptable risk area and ALARP area, and the risk level of 2.034 27×10-7 is the boundary of ALARP area and acceptable risk area. In the societal risk study, the intolerable line and the negligible line are determined, and the risk region is determined according to the ALARP criterion.

Key words: urban gas pipeline, individual risk, societal risk, acceptable criteria, as low as reasonable practicable (ALARP) criterion
