摘要
针对埋地燃气管道的风险评估,结合影响埋地燃气管道风险因素众多的特点,运用工程模糊数学理论,建立了埋地燃气管道风险程度的多层次模糊评价方法,确定了影响管道风险的基本因素。考虑了各类因素以及同类因素间的模糊性,并给出了因素类及因素间权重的计算方法。据此,可对埋地燃气管道的风险程度进行评价,从而有利于针对风险较高的管段采取行之有效的措施,防止事故的发生。
Since the risk factors influencing the embedded gas pipeline are numerous, fuzzy mathematics is applied in risk evaluation to establish hierarchy fuzzy evaluation method. Basic factors affecting the pipeline risk are determined. Take the fuzziness of factors of different categories and in-between factors of same category into consideration, their own weights are provided. Therefore, the risk of embedded gas pipeline could be evaluated. Accordingly, appropriate effective measures could be taken in time to prevent the potential accident possibly occurred at the risky section of the pipeline.
