Abstract: Applying strueture fuzzy theory, fuzzy uncorking possibility of a bridge which is loaded by the standard automobile load is determined.Furthermore, the fuzzy reliability of a bridge which is leaded by the same load is calculated,The result is consistent with the result of experiments.

Key words: reliability, bridge analysis, application of fuzzy theory

摘要： 本文结合某公路吊桥承载力的确定,应用结构模糊可靠性理论,推算了指定汽车标准荷载下失效的模糊概率,确定了该桥现行承载力指标的模糊可靠度,与实测结果符合较好。
