应用了基于模糊数学理论的评估法对桥梁损伤等级的评定进行了研究。首先用二级模糊综合评价的方法建立了桥梁评估的数学模型,并用损伤度来衡量桥梁结构或构件的损伤程度;然后采用分项工程、分部工程、单位工程逐级评定的方法对整座桥梁损伤等级进行评定;最后通过对一座受损桥梁进行损伤等级综合评定说明这种方法的适用性。利用模型评价结果,可针对性采取措施,提高战时桥梁抢修效率。

In order to assess the degree of damage to bridges in wartime,the evaluation for the structural damage degree of bridges is studied with fuzzy theories in this paper.A mathematical model is established in the light of the method of the two-level fuzzy synthesis evaluation,with the theoretical-damage values applied to measuring the damage degree of the structures and components of the bridge.The evaluation will be performed step by step,in the order of the subentry engineering,the subsection engineering and the unit work successively,thus completing the comprehensive evaluation of the whole bridge.Finally in the paper its applicability is proved by comprehensive damage level assessment of a certain bridge.By utilizing the results of the evaluation,the rush-repair efficiency of bridges in wartime may be much improved,with corresponding effective measures taken.
